Break out of your shell

[Robert Jenkins]

So i just picked up a few new books. "How to make friends and influence people." and " Think and grow rich". I know there are a few categories on here wehre people name good books, but i want something a little different. Books that helped you break out of your shell or helped you learn to deal with people.

I'm kind of a straight shooter (aka blunt) and don't easily understand emotional people sometimes. So is there something that really just CHANGED your outloook if you were similar?
