Who do you think you are?

Well,

if enough people keep telling you who they think you are, you might begin to believe it. To know who you are can be a very frustrating task. Sure, you are probably a lot of things to many different people. So if those people keep telling you who they think you are, I know it's hard, but don't let it bother you. If I were to believe all the things I am told I am... well, then I would never get to be me.

  I am me.
