Not living in fear is a great gift, because certainly these days we do it so much. And do you know what I like about comedy? You can't laugh and be afraid at the same time—of anything. If you're laughing, I defy you to be afraid.

- Stephen Colbert

Fear... can make you do more wrong than hate or jealousy. If you're afraid you don't commit yourself to life completely; fear makes you always, always hold something back.

- Philip K. Dick
