Popularity is a socially transmitted disease.
I'm not popular, and I don't care. Up 'round here, the "popular" kids are really nasty and horrible to everyone and I attempt to stay away from them as much as I humanly can. They love going out of their way to make you feel like crud. Then again, that seems to be the way with most popular kids, not just where I'm from.
I have two rings of friends, one of which is really the "loser" class, but I think those people have more style and "popularity" worthy traits than all of the "populars" put together. The other is a group of four, myself included, and we stick to ourselves. It's just easier and nicer. We're an odd bunch, and hardly seem like we could function as friends, but we're as close as they come.
Nice thing being, I don't care that I'm not popular. I'd much rather stay like I am instead of changing myself inside and out for a title that will only be with me for another year or so. Pointless.
If you want real popularity, be nice to the next Freshman you see or ask a "loser" to a dance. You might be suprised what you find out about yourself and your high school's social classes.
