"When adults say, "Teenagers think they are invincible" with that sly, stupid smile on their faces, they don't know how right they are. We need never be hopeless, because we can never be irreparably broken. We think that we are invincible because we are. We cannot be born, and we cannot die.

But that part of us greater than the sum of our parts cannot begin and cannot end, and so it cannot fail."
