You have knowledge and information in your head that other people want - you just don't realize it!  Most people take their own knowledge for granted and assume that "everyone knows what I know."  This simply isn't true, and once you realize that you have a lot to teach others you can begin to profit from that information online.

Selling information is one of the simplest business models, but is also one of the most effective.  You create an information product once and sell it over and over again.  Your profit margins are huge since your cost to duplicate the product are either zero (electronic product such as PDF or membership website) or very small in the case of a printed manual or report. 

To get started, just sit down and write out the things you know that others may be interested in.  Here's a few ideas to get you started:

• How to remove all viruses and spyware from a computer
• How to speed up an old computer and make it run like new
• How to lose 10 pounds in one month without exercising
• How to get a job without sending out resumes
• How to get a two-year old child to go to bed at the same time every night
• How to insulate your house in the winter months and save a ton of money on your heating bill
• How to have more romance in your life

You get the idea - people are willing to pay YOU money if you can save them time, save them money, make them money, or fix a problem in their life.  Sit down, find a good idea, write out an outline of your ideas, and then fill in the gaps until you have a value-packed report or manual.  Start marketing it everywhere you can think of, cash the checks, and do it all over again.  Your goal should be to have at least 20 different products - all bringing in income to you every month.
