“I was taught that to create anything you had to believe in failure, simply because you had to be prepared to go through an idea without any fear. Failure, you learned, as I did in art school, to be a wonderful thing. It allowed you to get up in the morning and take the pillow off your head.”
~ Malcolm Mclaren
