It's pretty important to me. Perhaps that makes me a shallow person, but that's just who I am. Every tiny flaw about myself bothers me.
I know that beauty is subjective, but what I want is to look in the mirror and see someone who's beautiful by my own standards. If I met someone who thought that, say, my nose is attractive, I would not only disagree with him, I would actually consider him to have very poor taste. My life would be a lot easier if I weren't like this, but it's just how I am. The best thing for me to do is to work around it, i.e. find ways to make myself more attractive.
