I have a filthy horrible secret....
I enjoy reading self-help books.
Really, I feel better now.
In all seriousness, there are some great self-help books out there. Even the not-so great ones can give you interesting perspective if you can stand to wade through the psychobabble. The late John Wooden is remembered in small part for saying that, "Five years from now, you're the same person except for the people you've met and the books you've read."
