On perserverance, 3.

"And this, really, is the story-within-the-story, because if you do not believe that hearts can bloom suddenly bigger, and that love can open like a flower out of even the hardest places, then I am afraid that for you the world will be long and brown and barren, and you will have trouble finding the light.

"But if you do believe, then you already know all about magic."

-- Lauren Oliver (from Lisel & Po)
