Science fiction author Ray Bradbury interviewed in 1972 by two college students driving him to a speaking gig.

From Blank on Blank:

You learn to live with your crazy enthusiasms which nobody else shares, and then you find a few other nuts like yourself, and they're your friends for a lifetime. That's what friends are, the people who share your crazy outlook and protect you from the world, because nobody else is going to give a damn what you're doing, so you need a few other people like yourself.
