It's about bullying. In the first verse, Amy says that she tried to fit in with the popular kids at her school but failed miserably and decided that you don't have to just live the way the popular kids live. In the second verse, Amy describes the cliques at her high school and what happens when you cross them. In the chorus, it looks like she is confronting the bullies by saying that she is better than they are by not stooping to their immature levels when they bully her. In the bridge, she basically says that if we all looked the way the popular kids do, the world would be boring.
