There is a crack in everything. That's how the light gets in.
If you want to give light to others, you have to glow yourself.
We are all in the gutter, but some of us are looking at the stars.
The most precious light is the one that visits you in your darkest hour!
The sun does not shine for a few trees and flowers, but for the wide world's joy.
Keep your face always toward the sunshine - and shadows will fall behind you.
The only way to deal with darkness is to become light.
