Are you really hard on yourself? I am. I work hard to do things the "right" way, to get a project "right" the first time, to say the "right" things, to look the "right" way, etc. And because I feel like I'm trying so hard, when I do mess up, I don't handle criticism very well. I've been bent this way my entire life and it has harmed me more than it has done me any good.
