As soon as things get difficult, I walk away. That’s the great secret of creativity. You treat ideas like cats: you make them follow you. If you try to approach a cat and pick it up, hell, it won’t let you do it. You’ve got to say, ‘Well, to hell with you.’ And the cat says, ‘Wait a minute. He’s not behaving the way most humans do.’ Then the cat follows you out of curiosity: ‘Well, what’s wrong with you that you don’t love me?’
Well, that’s what an idea is. See? You just say, ‘Well, hell, I don’t need depression. I don’t need worry. I don’t need to push.’ The ideas will follow me. When they’re off-guard, and ready to be born, I’ll turn around and grab them.
