Oh my gosh! This is me and one of my friend's theme song! We love it. I think it really explains that all you have to be is yourself and no one else. You are you, so stop pretending to be someone else to make yourself look "cool", because you can't change who you are. You can change the way you walk, talk, or look, but you can't change who you are inside. I love this song and it's saying something true. Stay yourself, change for no one.
