Just a different twist and similar to what brat wrote...
Write a novel. Incorporate what you have learned into the plot line. Then sell the book via e-book. Keep the price
under $4.99 (The price that paperbacks
use to sell for).
Plan on writing a series of a minimum of 3 books - Five would be best. Get people hooked and then you have a guarantee reader base.
Some good examples are:
Patriots Has ~4 novels out there that are overlapping plus a blog now
299 Days - Best example nine books plus a blog now
Enemies Foreign & Domestic has 4 books out there plus writes articles for $$$$
Others?
The secret is to knock out a plot line and then fill in the blanks. Simple right
