No one ever came up to me and said: "You need to reshape your body, to lose weight, or to be more outgoing, or less outgoing". We were just allowed to be us, and I think at the end of the day, isn't that the whole point of being a human being? To be allowed to be yourself, to be accepted the way you are?
Don't be afraid to be yourself just because you're not like everybody else in class. If you want to dye your hair green and that's what makes you happy, then dye your hair green, no matter what other people might say about it. Not everybody is going to like you - that's the world we live in; that's reality.
I saw one of the absolute truths of this world: each person is worrying about himself; no one is worrying about you. He or she is worrying about whether you like him, not whether he likes you. He is worrying about whether he looks prepossessing, not whether you are dressed correctly. He is worrying about whether he appears poised, not whether you are. He is worrying about whether you think well of him, not whether he thinks well of you. The way to be yourself. . . is to forget yourself.
