Some of the comments here are pretty funny. I especially like the ones that basically imply (or outright say) that "science doesn't apply here." That's a bit like saying "reality doesn't apply here." I would, though, agree with the people who say that most self-help books don't offer any help, but instead aim to motivate people. Unfortunately, they mainly motivate people to buy more self-help books, because reading about other people's successes is a pretty compelling substitute for experiencing actual success.
