Well yea, they make people more interested in them. Then, unless they're complete jerks and people start and bullying them, they start doing pretty good. The important thing is to fit well in your own skin.
And speaking of that popular kids and "looking like them if you want to be popular", why are they popular? I can't really say why is it, but I can guess. Is it because they have rich parents? They have good grades (ROTFL )? Or they have something special that makes them interesting?
From my point of view, being different is a power. Just be careful with that "I don't give a f***!" attitude. Too much will make you a lonely weirdo, and not enough will make you a snob, just a wannabe to laugh at.
