Falling in love…aaahh what a wonderful experience the first flushes of love are. The heart starts pounding, our temperature rises, and the butterflies begin fluttering whenever the girl/boy of our dreams enters the room. The world looks so…well…rosy. Not only that, life suddenly becomes much more exciting. From my own experiences the heady excitement of first love really did my head in - for some reason commonsense flew out the window…well in the short term anyway. I started accepting things that I normally wouldn’t, pulled away from my old friends, and started to lose a part of myself to accommodate the other person.

I followed my heart when on reflection I could’ve saved myself quite a bit of stress had I known a few more things about sharing my life with someone. I never really asked the important questions such as who would be the major breadwinner, compared our values or really planned for the future. I simply followed my heart and went with the flow in blissful abandonment.

What do you really know about your future life long mate? Do you know what their favourite piece of music, colour, outfit, book, holiday destination is?

What about their likes and dislikes? Do you know what their level of patience and understanding is, are they aware of yours? Are they flexible or inflexible thinkers and do you recognise whether you are or not?

I’ve listed 10 basic points to ask each other before you reach love’s point of no return. You could treat this as a date, and also as an opportunity to really get to know each other on a deeper level. Above all be tactfully truthful, treat what the other has to say with respect, and never assume the other knows what you’re thinking.

If this sounds a bit clinical, consider it as a blueprint of your future lives together. Ever heard the comments “I wish I’d known what I was getting myself into.” Or “I wish I knew then, what I know now.” Or “I just can’t understand her/him.”

Here are the points:

1. Ask each other what your values are on a scale of 1 - 10.

2. Ask what you really do not value on scale of 1 - 10.

3. Do you both want children? If only one wants children, is there an alternative and is this issue negotiable?

4. Who will be the breadwinner after the baby is born? It’s not necessarily dad anymore. Are you both okay with who will be the major breadwinner?

5. Assuming you both were employed prior to children, ask yourselves once you become a parent how long will it be before you return to paid employment. I make this point because from experience that whilst the majority of couples I’ve met are ok with the traditional scenario of the wife remaining at home with the children, some men have resented this.

6. What do you expect from each other - in sickness and in health? Ask each other what you expect from them; in return let your partner know what you will personally bring into the relationship and what you will continue to bring to the relationship.

7. What will you forgive/not forgive of each other’s behaviours, for example, infidelity or lying?

8. Do you have a hobby you could both share? List all the really wonderful things you could do together.

9. Will there be occasions when you want to do things alone? For example, boys/girls night outs, fishing trip with the boys/girls etc. Is this acceptable to you?

10. Is there anything that annoys you about your partner already? Are you willing to accept annoyances?

Secretly thinking that your partner will come around to your way of thinking sooner or later could possibly be setting yourself up for disappointment. There’s also the risk of blame and anger if you’re unable to change something you assumed you could.

Accept that nothing in life is perfect - life could be said to be is perfectly imperfect.

It is true that this article is directly more towards
teleclasses, yet, the ten tips also included hold true for
any type of electronic Learning (eLearning) marketing and
promotion.

Teleconferences, also known as teleclasses or teleseminars
depending on the presentation format, are the second hottest
marketing delivery technique for 2004. This delivery format
satisfies the yearn to learn and opens an exchange to
unbelievable global portions.

Previously called distance learning, the teleclass format
actually began in the mid-1990s through higher learning
institutions. Now, without leaving your office or easy
chair, you can put on a headset, lean back and learn. No
parking challenges, gas usage, or travel time required.

Technology is exploding in this part of the communication
industry. In 2003 this market tripled their service
features for leaders, use and availability in on the
incline, and the attendance limitations of 30 a few years
ago now expands to 150. And in 2004, the market continues
to show that it will double even 2003s number.

Teleconference phone numbers are still limited to
availability in only certain states, like Florida and
Nevada. The pressure for other states to add
teleconferencing services at these reasonable rates is not
there yet. The bell is toiling louder every year.

Currently, you can purchase a personal-use 24/7 line in the
range of $600 a year. Alternatively, you can rent a line by
the hour from $10 up or even share a line.

You can find no cost teleconference lines, like
http://www.mrconference.com. I found these services less
than desirable. Many times, you get disconnect if you don’t
talk every 10 minutes or you are blocked from entering the
call if their lines are full.

No, teleconferencing will not take the place of “being
there”. Yet, some teleconference leaders can just about
bring you physically into feeling that same experience.
If you have never experience a teleconference, I recommend
that you do, but don’t just try one. The greatest benefit
to learning by phone is that you listening skills will reach
new heights quickly.

1. If you produce your own e-newsletter or printed
newsletter, you can add a teleconferencing announcement
section.

2. Contact other e-newsletter or printed newsletter editors
and ask to have your teleconference announced in their
issues. You can swap for the space (your ad for their ad in
your e-newsletter), barter for a space in your session,
offer an affiliate option, purchase the space or pay per
click. You want to advertise with your focus target.

3. You can also run pay-per-click search engine ads. The
Google AdWords program is a great place to start. If you
purchase an ad analyzer software (average $100) or a service
(average $19.95/month) you will save time and make less
mistakes. It will also save you hours of analyzing your
own. Look for the ads that you pay more than a nickel each.

4. Place notices all over your web site — especially your
main page. Remember, this is a passive method (meaning that
you still need to get visitors to the site before they can
read it).

5. Write and distribute Internet articles on the same
subject. Unable to write, hire a ghostwriter. Allow three
months for this process to begin working. You will also want
to write and distribute at least three articles a month.
Don’t ignore this marketing avenue. This method is number
five on the top promotional methods for 2004.

If you are writing marketing articles a great media-posting
site is: http://www.ideamarketers.com. Each site has it’s
own guidelines and speciality topics. To find other media-
distribution sites, visit http://www.google.com and search
on “submit article” and “[your topic]“. Use your bio or
resource paragraph, usually limited to five or less 60-
character lines, to entice readers about your teleconference
offer.

6. Distribute your information globally. Whether using
Internet articles, advertising or any of the other methods
mentioned in item 2 and item 3 above. Find places in other
English-speaking countries like the United Kingdom, Canada,
Australia, and New Zealand.

7. Announce your teleconference calls on other people’s
teleconferences. You can slip it in with a question, when
you are responding to a “what do you do” segment, or ask the
leader before hand for an opening as a complimentary service
to theirs, for bartering, or even a commission.

8. Add a promotional paragraph to all your outgoing e-mail
signatures.

9. Do you below to any discussion lists or boards that allow
you to post your teleconferences. Some do and some don’t.
If you are not sure, ask the group’s moderator. Off a
special price for members on the list.

10. Write a press release for each teleconference. Become a
member of PR Web http://www.prweb.com/ — membership is
free. I found this site to be the best for a Google pickup.

11. Begin a list of all your local newspapers that offer
free community event announcements. Find out what their
deadline are and submission requirements. Create what they
need and send it to them about a week or two before their
deadline.

As you get acquainted with working with your local
newspapers, you can then begin to start expanding to other
cities and locations. Choose a city and then do the same.
When done, choose another city. Start a binder with all the
information and set up your Internet browser with categories
and your e-mail software with a separate “Community
newspaper” section to keep yourself organized.

Eventually you will want to delegate this over to a Virtual
Assistant.

12. Write a telephone answering script and change your voice
mail frequently to mention your teleconferences.

13. Use fre*e offers to attract people to come and find out
additional information about your teleconferences. You can
use an ebook, ecourse, special report or even a white paper.
A transcript of another teleconference, if the same target
market, would also work well.

14. List your class in teleclass directories. Some of these
listing posting sites require that you complete “their”
teleclass-leading course. A big downfall in time and
expense. These include:
http://www.seminarannouncer.com
http://www.teleclass4u.com
http://www.teleclasslive.com
http://www.teleclass.com
http://www.thefeelgoodplace.com/freetele.htm
http://www.Yahoogroups.com has over 30 places to post your
listing (depends on your topic).

15. If you give speaking engagements or attend seminars,
give out flyers on your teleconference program. Works well
in networking groups too. Take the flyers to the libraries,
senior and civic centers..

The great luminaries of human society clearly understand what the creative forces
put them here to contribute. The mediocre members of human society, on the other
hand, never decipher the purpose code. Of course, purpose is more than a job or a
career; purpose is more than some specific role like father or mother. For many
people, however, the most difficult piece of their purpose to decipher is the one
called career.

So, maybe you want to start a business from home; maybe you want to harness
internet traffic to highlight some cause in which you believe; whatever your hope, it
starts with aligning yourself with your inner purpose. Once you have aligned–even
slightly more than now–with your purpose you will begin to see amazing
coincidences start to happen that appear to be designed with your well-being in
mind. Perhaps some internet advertising
company will arrive to show you how to make money doing the type of
vocation that is to you a vacation; perhaps an investor will fall into your lap for a
business idea upon which you have been working. The bottom line is that once you
begin to align yourself with your divine purpose, you will find the generosity of the
universe becomes open to you. This is because the universe that made you did so
with the intention of increasing well-being.

The difficulty of decoding purpose is only enhanced for people who have talents of a
creative nature. A friend of the author has been struggling for years to decide what
his career should be. He has tried starting a business and failed. He has tried
working up the ladder of a corporation and failed. It appears that he has tried
everything he can think of except for the obvious: creative enterprise. He knows his
talents are in creative enterprise–specifically acting–but he continuously doubts
that his ability is strong enough to sustain a paying career in the field he loves. The
sad result of his self-doubt is that he has wasted his money, credit, and dignity on
one poor fit after another. He believes he is a failure when in actuality he is merely
being taught by life the one difficult fact of success: follow your talent.

Joseph Campbell–the popular academic–used say “follow your bliss,” but director
George Lucas revised that advice to “follow your talent” in an interview with Charlie Rose last
spring (2005). He told the story of his haphazard fall into moviemaking. He didn’t
really know what he was getting into, but after he started doing it, he found he was
as good as the best and better than most. The result of his choice to follow his
talent has made him one of the richest directors in Hollywood history and has made
our country and world richer for his having been here. Isn’t that the kind of legacy
everyone is after? Of course, not everyone is meant to be a superstar director like
George Lucas, but why can’t everyone be the very best that is in them to be? The
answer of course is that they can if they choose to follow their talent.

So, you are one of the people who has been cursed–as you may see it now–with
artistic talents, but with few talents for more practical roads. What do you do next?
For certain, do not attempt to build the city of your life around the oasis of someone
else’s purpose because if you do, that luxuriant oasis will ultimately reveal itself to
be nothing more than a mirage.

The first affirmative step you can take is to embrace your purpose and set a clear
intention to fulfill it. While it can’t be proven that every person who has ever set a
clear intention got what they were after, it can be shown–empirically mind you–
that no real success has been wrought from uncertain intentions. While George
Lucas may not have known that film was where his talent lay in the beginning, once
he learned the talent was there, he pursued it from then on by choice, not by
accident. The list of luminaries who prove this rule is indefinably long.

Any namable success can be shown to have followed this first rule: clear intention.
Any exception you think you can name ends up, upon further investigation, to be a
fluke rather than a success. Flukes are not happy or content people, successes–in
the area of their success at least–are happy and content. So it is with you. The
nature of happiness is that all of the doors lying before the path look like labrynths,
mirrors, and gargoyles, but once happiness has boldly been committed to, those
foul looking centurions reveal themselves to be friends and allies.

It is important to know about what is on your personal credit report even before looking to make any kind of purchase or apply for any type of credit. A good credit report can give you a great deal of purchasing power while a less than acceptable personal credit report can have a great deal of influence on how much interest you may end up paying or if you can even get credit or be allowed financing at all. While you may think that you have excellent credit, it pays to check and find out if there are any errors or discrepancies that can be fixed before attempting to get financing on any purchase.

You should check your personal credit report at least once a year by examining reports from each of the three major credit bureaus, which are Experian, Equifax and Trans Union. Many times you can view your reports for under $10.00 or even for free. In fact, if you are checking your report because you have been turned down for credit by a lender, you can view your credit report for free within 60 days of that decision.

When viewing your personal credit report, you should look at all of the information as a potential creditor would see it. Make sure that if you pay all of your bills on time, the report accurately displays this information. If your debt is near your credit limit, this is not looked on favorably. Your credit rating is especially important if you don’t have an extensive personal credit history yet. If you apply for a lot of credit during a short period of time, this is factored in your personal credit report and can have a damaging impact on approval or interest rates.

If you happen to find a discrepancy on your personal credit report, make sure that all of the information that is listed really belongs to you and that the balances are current and correct. If you find that a credit report still lists old loans that have been satisfied, contact the credit bureau and request that it be adjusted. Keep in mind that information including bankruptcies and collection agency referrals are kept on personal credit reports for between seven and ten years. If you find any errors on your personal credit report, the credit bureau is required to investigate the incorrect entry and adjust it accordingly.

Some of the most obvious problems include the need to:

* find a suitable house to purchase

* plough through complicated financial information

* choose an appropriate mortgage that will cover the cost of the house and is within your own strict budgets

* save up enough money (usually whilst still renting another property) to cover a mortgage deposit

* deal with unfamiliar legal fees, surveys and other costs

* make a realistic offer on your prospective new home

* waiting to see if the offer is accepted

* complete the purchase

* move and get settled in the new house, with whatever decorating/rebuilding is required

Given these factors, it is perhaps not surprising that first-time buyers can be the first to get spooked by changes in the housing market.

First-time buyers (FTBs) make up an extremely important sector of the house buying market, and many analysts view them as the life blood of the whole housing market. Without them a housing slowdown or even collapse of the system is inevitable. Recent reductions in the number of FTBs purchasing houses, with Scotland achieving its lowest annual total for nine years, and the increasing struggles experienced by FTBs trying to get onto the first rung of the property ladder will have serious knock-on effects, which are already being experienced around much of the country.

National Savings and Investments (NS&I) Senior Savings Strategist Dax Harkins said: “Despite a recent cooling house market, house prices have continued to outstrip both savings rates and incomes over the last year which means potential first-time buyers need to start saving sooner and harder to get into the market.”

Whilst house prices continue to increase at a faster rate than people’s incomes there will be fewer people able to afford a house.

In a recent study NS&I found that the average length of time required by FTBs, to save for a 5% mortgage deposit, ranged from five years in East Anglia, to three years, nine months in Scotland, with the average being four years and nine months, this is nine months longer than a year ago. The average age of first-time buyers also has increased, going from 37 from 31 three years ago.

The property website Rightmove has warned that the housing market could remain static for several years whilst it waits for the incomes of FTBs to catch up with the housing prices.

Miles Shipside, commercial director of Rightmove, said “As many sellers are refusing to part with gains they have made, buyers are forced to make up the affordability gap…The reality is it will take seven years of static house prices and wage inflation to bridge this affordability gap.”
Marjorie Townsend, head of Edinburgh-based Lindsays Residential, says: “It was recently reported that an average home in Edinburgh costs seven times the income of the majority of nurses. This is a shocking statistic.”
With over one in six FTBs turning to relatives and more high street lenders offering 100% mortgages, or even 102% from Lloyds TSB and Scottish Widows, to help buyers get onto the property ladder, some may be able to squeeze onto the first rung, but end up with long-term crippling debt in the process, fuelling the continued house prices inflation.

Various banks have come up with innovative methods to help facilitate the ability of FTBs to purchase a house which, whilst not addressing the real problem of house prices, will allow more people to own their own home.

A guarantor mortgage can increase the amount that can be borrowed, as long as the borrower’s parents have enough income to cover all their own debts, plus their child’s mortgage each month; however the parent will not have to make any payments themselves unless their child’s mortgage goes into arrears.

An offset mortgage could mean that money from a parent’s savings account can be offset against their child’s mortgage. Although the parent would not receive interest on their savings, the reduction in the amount to be paid by their child could make a big difference, and they would not incur tax on the amount either.

A ‘Professionals’ mortgage is a possibility for certain workers, which allows them to borrow more than their initially low-pay career would usually make them eligible for, on the understanding that their future pay will increase rapidly as they become high earners.

Whilst some may urge for caution to prevent the possibility of building up financially crippling levels of debt, others see a need for buyers to act fast.

Marjorie Townsend, of Lindsays Residential, believes: “The best advice for first-time buyers is to move quickly …There really is nothing to be gained by waiting for a competitive closing date, which will drive the price up. There are lots of sellers out there who are eager to sell and whose particular circumstances may require a quick transaction.”

Overall it seems that the situation for FTBs will continue to prove difficult unless a major change occurs that bridges the gap between income and house prices for those in most need. Recent government initiatives such as the Shared Equity scheme, that allows part ownership of property, may go some way to enabling some FTBs to start out, but Ed Davey MP, the Liberal Democrat housing spokesman, believes the policy could make housing even more expensive, “It seems to be looking at the demand side which could stoke house price inflation and make the problem of affordable housing even worse.”

Until the issue of supply and demand is addressed, there will continue to be problems. According to the Barker Review, which was published in April, up to 140,000 new homes need to be built each year in the UK if supply is to keep up with demand. Even if new homes are built at this rate, the time taken to stabilise the market will mean further delays for prospective new buyers who want to own property.

There are many singles’ websites that offer true free services. They provide registration and access to their services absolutely free without any time limitation or restriction. Singlesstop.com, one of the Internet’s largest, completely free, singles’ dating sites, is not a devoted dating site. They provide advice on a number of related topics, including relationship maintenance, flirting, etc. One of the most attractive features of this website is a question-and-answer section. They even offer a review of the various dating sites.

Matchdoctor.com, a leading singles’ and friends’ networking site, is noted for the quality of their services. The site has many features that most other paid dating sites do not offer. Hookup.com, a devoted singles’ website, offers many interesting services like the facility to send private messages, chat rooms, and surveys.

Singles’ sites that target specific customers commonly charge for their services. However, there are many sites that offer free services to Christian and Jewish singles, like Christiancafe.com. There are many sites that offer similar services to the Asian and black communities.

SQL Server supports a number of methods that can be used to enforce data integrity. These methods include defining datatypes, NOT NULL definitions, DEFAULT definitions, IDENTITY properties, rules, constraints, triggers, and indexes.

Datatypes

A datatype is an attribute that specifies the type of data (e.g., character, integer, binary, etc.) that can be stored in a column, parameter, or variable. SQL Server provides a set of system-supplied datatypes. However, users can also create user-defined datatypes based on the system-supplied datatypes. System-supplied datatypes define all of the types of data that can be used with SQL Server. Datatypes can be used to enforce data integrity because the data entered or modified must conform to the type specified for the object. For example, a name cannot be stored in a column defined with the datetime datatype, as a datetime column can accept only date values.

NOT NULL Definitions

The nullability of a table column determines whether the rows in the table can contain a null value for that column. A null value in a column does not mean that the column has zero, blank, or a zero-length character string such as ” “. Null in a column means that no data has been entered in that column. The presence of a null in a column implies that the value is either unknown or undefined.

The nullability of a column is defined while defining the column or while creating or modifying a table. The NULL keyword is used to specify that the column will allow null values. The NOT NULL keyword specifies that null values will not be allowed in the column.

DEFAULT Definitions

Each column in a row must contain a value even if that value is null. However, certain situations exist when a row is inserted in a table, but the value for a column is not known or the value does not yet exist. If the column allows null values, a row with a null value for that column can be inserted in the table. In some cases, nullable columns might not be desirable. In these cases, a DEFAULT definition can be defined for the column. Defaults specify what values are automatically inserted in a column if a value is not specified for the column when inserting a row in the table. For example, it is common to specify zero as the default for numeric columns and N/A as the default for string columns.

When a row is inserted in a table with a default definition for a column, the SQL Server is implicitly instructed to insert the specified default value in the column if a value is not specified for the column.

IDENTITY Properties

The IDENTITY property is used to define a column as an identifier column. An identifier column contains system-generated sequential values that uniquely identify each row in the table. A table can have only one identifier column. Identifier columns usually contain values that are unique only within the table for which they have been defined. In other words, other tables containing identifier columns can contain the same identity values used by another table. However, the identifier values are typically used only within the context of a single table, and the identifier columns do not relate to other identifier columns in other tables.

Constraints

Constraints are used to define the way that SQL Server automatically enforces the integrity of a database. A constraint is a property assigned to a table or column within a table that prevents invalid data values from being entered in the specified column(s). For example, a PRIMARY KEY or UNIQUE constraint on a column prevents a duplicate value from being inserted into the column. A CHECK constraint on a column prevents the column from accepting a value that does not meet the specified condition. Moreover, a FOREIGN KEY constraint establishes a link between data in two tables.

Rules

Rules perform some of the same functions as CHECK constraints. However, CHECK constraints are preferred over rules. Rules are provided only for backward compatibility. CHECK constraints are more concise than rules. A column can have only one rule applied to it. However, multiple CHECK constraints can be applied to a column. CHECK constraints are specified while creating a table, whereas rules are created as separate objects and are bound to the column.

The CREATE RULE statement is used to create a rule. Once a rule has been created, it can be bound to a column or a user-defined data type by using the sp_bindrule system stored procedure.

Triggers

Triggers are special types of stored procedures that are defined to execute automatically when an UPDATE, INSERT, or DELETE statement is issued against a table or view. Triggers can be used to enforce business rules automatically when data is modified. Triggers can also be used to extend the integrity checking logic of constraints, defaults, and rules. However, it is recommended that constraints and defaults be used instead of triggers whenever they provide all of the needed functionality.

Indexes

An index is a database object that orders the values of one or more columns in a table. An index provides pointers to the data values stored in specified columns of the table and orders the pointers in the specified order. When rows are requested from an indexed table, the database searches the index to find a particular value and then follows the pointer to the row containing that value.

Types of Data Integrity

SQL Server supports the following four types of data integrity:

1.Entity Integrity

Entity integrity defines a row as a unique entity for a particular table. Entity integrity enforces the integrity of the identifier column(s) or the primary key of a table (through indexes, UNIQUE constraints, PRIMARY KEY constraints, or IDENTITY properties).

2.Domain Integrity

Domain integrity validates the entries for a given column. Domain integrity can be enforced by restricting the type (through data types), the format (through CHECK constraints and rules), or the range of possible values (through FOREIGN KEY and CHECK constraints, DEFAULT definitions, NOT NULL definitions, and rules).

3.Referential Integrity

Referential integrity maintains the defined relationship between tables when records are entered or deleted from the tables. In SQL Server 2000, referential integrity is based on relationships between foreign keys and primary keys or between foreign keys and unique keys (through FOREIGN KEY and CHECK constraints). Referential integrity ensures that key values are consistent across the related tables.When referential integrity is enforced, SQL Server prevents users from adding records to a related table if there is no associated record in the primary table. Users are also prevented from changing values in a primary table or deleting records from the primary table if there are related records in the related table.

4.User-Defined Integrity

User-defined integrity is used to define specific business rules that do not fall into any of the other integrity categories. All of the integrity categories support user-defined integrity. All column-level and table-level constraints defined in CREATE TABLE, stored procedures, and triggers are examples of user-defined integrity.
