I'm an author who wrote an Amazon "bestseller" -- it was the #1 Culture book in the store for six months, and the #1 Technology book for about one month. (http://amzn.to/infodiet http://amzn.to/infodiet) I sold more than 4,000 books (closer to about 15,000), but have basically made a relatively comparable amount of money from royalties from the book. That said, if you're writing a book looking to profit from the sales of the book, you're doing it wrong. I easily pull in six figures for speaking fees that result from having written a book. I wasn't getting those offers before having written the book. Maybe fiction is a bit different. But you can always find a way.
