The man who wrote the 4 Hour Body which is actually a pretty incredible book which I've taken bits and pieces from but also this interview is actually very inspirational especially for those that do Photography or Video, maybe even both like Chase Jarvis because it dives into the world of business.

More so it presents a way in which to survive and find a means to survive in many ways in this materialistic kind of world. In a sense the book gives you a sort of starting point but rather if you have something working already it's probably best to take bits and pieces, self help books and the like are rarely going to apply to literally an entire population.
