The City of Ember

by Jeanne DuPrau

What you get is what you get. What you do with what you get, though . . . that's more the point,

The main thing is to pay attention. Pay close attention to everything, notice what no one else notices. Then you'll know what no one else knows, and that's always useful.'

The trouble with anger is, it gets hold of you. And then you aren't the master of yourself any more. Anger is.'

Everyone has some darkness inside. It's like a hungry creature. It wants and wants and wants with a terrible power. And the more you give it, the bigger and hungrier it gets.'
