This isn't probably going to help much (if any), but I feel that way too, sometimes. But then I realize that there are things I have more than other people, things that make me different, make me ME. And somehow, that's even better than winning contests or having recitals or anything.

I think it's normal to be a little envious. There's always that girl who is prettier, nicer, more popular, smarter, whatever-er than us, but we'll always have something more, too. It DOES get annoying when everyone is all over her when we're standing right there, but when you find something you have that you're really proud of, I'm sure it wouldn't bother you as much.

Someone once says something along the lines of... "no one's better at being you than you", and I always remember that line every time I need encouragement to be more of myself. :)
