What important-to-you character trait of yours would you sacrifice to gain what important character trait you wish you had? (if you had to, heh)

I don't know what I could, or would, give up to gain something else. If I had anything I felt I could part with, I'd part with it to gain more discipline, to gain more confidence, to gain more feeling for other people, to have less fear of failure or of trying and failing. All the character traits I have I wouldn't want to part with. Giving them up would make me less, and I wouldn't know if what I would gain would compensate for that loss. Sometimes you can't compensate, sometimes you must simply be something else. I'm just not sure I'd ever be prepared for it.
