“Doctor, you don't know what it is to doubt everything, even yourself. No, you don't; you couldn't with eyebrows like yours.”

“You can be the most beautiful person in the world and everybody sees light and rainbows when they look at you, but if you yourself don't know it, all of that doesn't even matter. Every second that you spend on doubting your worth, every moment that you use to criticize yourself; is a second of your life wasted, is a moment of your life thrown away. It's not like you have forever, so don't waste any of your seconds, don't throw even one of your moments away.”

“There is no magic herb that makes a brave man. Courage is knowing that what you do is necessary. Don't doubt yourself, Shadow. There is more valor in your heart than you realize.”

“If you reveal everything, bare every feeling, ask for understanding, you lose something crucial to your sense of yourself. You need to know things that others don't know. It's what no one knows about you that allows you to know yourself.”
