Seriously, I think self help books are 90% poppycock. While I know there are a few books that can be helpful, I think that most of them are published editions of the "shit i should already know" type of information. I think its easier for people to seek help outside of themselves (nothing wrong with that), and so these books don't teach you anything NEW, they just remind you of what you could already be doing.
This, for example, is a book that could probably help with some stuff if you happen to be someone who is in the process of embracing minimalism (i.e., ME).
This one is more fluff (Sorry, Bethenny).
