Am I just making a fool of myself?

I'm 13 years old, I'd consider myself "pretty," I don't ise a lot of make-up, I'm very short and I'm happy with my "average" weight. I dress a little old for my age, but fashionable. For example, I don't wear sweatshirts and graphic tees, I wear flattering jeans and a flowy shirt. I sing and act, I'm always in community theater (hard-core stuff man!) and I'd consider myself fairly talented. But I'm VERY spastic and jumpy and not afraid to be an idiot in public. My friends think it's hilarious, especially when I fall down, (I got my clutzy habits from my mom :)) but what do guys think? Am I just being an idiot and being that girl they never want to be seen with? Should I tone it down or is being myself good and if guys can't accept that than they're not right for me?
