Me, I'm not much good at (or for) anything, and I have the lack of confidence to back it up. Even if I were halfway decent at something, I wouldn't know how to go about acting like I was.
Is confidence something a person either has, or hasn't? Can it be developed or cultivated or learned? I know that Tony Robbins and some of those other late nite TV infomercial people say you can, but I've read a number of their books, and in general when I'm done I end up feeling worse than before. So, I dunno, y'know?
