Hey, you're great just the way you are. Don't listen to what anyone else says, because you aren't them, you're you, so it doesn't matter what they think. Appearance isn't everything, either. Some of most attractive people have disgusting personalities that keep people away like bugs avoid from Raid.
You don't need to change yourself. You are you, and you are perfect just the way you are. Remember that you're the one who matters, so it's okay to be different, unique.
My point is that people are like geodes. The outside can be pretty, yes, but the real treasure lies with the beautiful gems on the inside.
