Hmmm... For my experience, confidence is just something you feel that exudes from inside - a belief in yourself (as interesting, funny, clever...whatever). If you have to 'point it out' to me, you don't really have it.
So what are the things you appreciate about yourself? Not the physical stuff, but what lies beneath? And I'm not talking about 'soul-bearing' or anything ao intense; just the things you like about yourself.
