Actually I didn't know there was a book about that. I remember reading a post of a guy doing that here on HN though. I had some savings and an opportunity arose, after some serious doubts and thinking, I took the leap. But for those who have a startup or do freelance work, I think it's highly probable to be able to do it as well. I have also a friend who does UI/UX web development who's been doing this for a couple of years too.
