Fear was absolutely necessary. Without it, I would have been scared to death.

I've been knocked down more than any heavyweight champion in history.

If you don't learn how to be scared, you'll never really learn how to be brave.

Ghosts are the only ones who never have to feel scared. Because the worst thing in the world has already happened to them.

Sometimes, something will startle me, and I secretly hope it's a zombie.

When you're scared - and I mean really scared, not just hearing a noise in the night, or standing toe to toe with someone twice your size who wants to pound you into the earth - it feels as if you're being injected with darkness. It's like black water as cold as ice settling in your body where your blood and marrow used to be, pushing every other feeling out as it fills you from your feet to your scalp. It leaves you with nothing.
