For the most part, I like myself a lot, but I wouldn't mind having a smaller nose. Its a bit on the large side, but I've learned to accept it. Oh yeah, and I would love to lose these damn chipmunk cheeks. I swear my face looks like I weigh about 50 punds more than I actually do.
Personality-wise, I guess I wouldn't be adverse to being a little less sensitive, I'm always concerned about saying the wrong thing and upsetting someone. It eats me up inside to know that I may have caused another person to look at me in a negative light. Sensitive probably isn't the right word, but I can't think of the correct one right now.
