Design is play.

[About Massimo Vignelli] "He hasn't worked one single day of his life because for him, it's just so much fun to work. It's like for him, there are no weekends, there is no vacation, it doesn't matter. He is happy if he is at his desk, or at least with his pencil and his piece of paper."
