Who's the perfect girl to be when moving to a new school? Please read on.?

We'll next year i am transferring. My reputation at this school is pretty sucky, now I know what not to do. like, don't tell every guy you like that you like them, and don't become obsessive. :). Before i lived where i am currently attending school i was a total brat. I was evil and stupid. i was annoying and DUMB. So, when i came here I changed. I like myself better now but want to change more. and no, its not i need to "be myself" i am tired of this me. i am moving to a school where they don't know me. So i can make me fresh. start over. who's the perfect kinda girl to be.? we all know one, the nicest girl in the school. who gets the guy she wants. who smiles pretty. i need to know her inside and out to become her. thanks, :)lol
