Stay true to yourself
Everyone's different. Everything from your appearance, to your laugh, to your personality is one-of-a-kind. When you stay true to yourself you can do anything. Have your own style, dare to be unique, paint your own world and do your own thing. Life wouldn't be fun if everyone were the same right?
