What should I change about myself?

You shouldn't change anything about yourself, you are wonderful just the way you are. But if you want to feel better about yourself there are little things you could do. What works for me when I want to change up my appearance is getting a haircut or changing the way I apply my make up. I actually think your hair already looks nice, but maybe you could grow the length out and get a side fringe (bangs). I don't mean to ume but it looks as though you don't really wear make up, I was totally clueless when I first started (at 11, aha don't judge me) but youtube really helped.
