The Instant Internet Income

I've seen a DVD about The Instant Internet Income.
It's quite interesting. It tells about how we can do a business on Internet.
For example we can sell e-books.
At first, we should think what about we want to write a book. It can be
anything. For example Fishing. If you can't write a book, you can find a ghostwriter,
who will write it for you for peanuts.
Secondly, we should find a market. Look for relatively large groups of people
who are passionate about something to the point of irrationality, who spend money.
And then find as much information as it possible about market you've chosen.
How to find an information? Look at magazine, keep your ears open - talk to any
fanatics you come across.
Look for conventions, clubs and associations, watch TV and look for "crazy" people.
And finally we can advertise it on Google, for example.
