How to be less of a loser?

So I'm a 16 year old girl. I am unattractice, antisocial, unintelligent, and untalented. I don't do anything well. Meanwhile I look around my life (and my school) and I see people kids my age who are on television, selling a lot of records, or doing something amazing in the clroom. I am not exaggerating either. These are the kids I have to compete with and I am a baseline failure. I don't know what to do! I want to be something but I am so behind. Please help! Besides working hard (which I do but I can't seem to catch up), what else should I be doing to be less of a loser?
