" You are perfect. "

" I'm not perfect. I'm fat and I have big eyes. My lips are too thick. I'm small and my voice cracks when I sing. I'm not a girl. I'm ugly. "

" You don't have to be anything to be perfect because the way you are made you perfect in my eyes. " 

You are not perfect when you think you are. You become perfect when somebody else looks at you that way.
