His commencement speech at University of the Arts is pretty great:
The moment that you feel that, just possibly, you're walking down the
street naked, exposing too much of your heart and your mind and what
exists on the inside, showing too much of yourself. That's the moment
you may be starting to get it right.
The things I've done that worked the best were the things I was the
least certain about, the stories where I was sure they would either
work, or more likely be the kinds of embarrassing failures people would
gather together and talk about until the end of time. They always had
that in common: looking back at them, people explain why they were
inevitable successes. While I was doing them, I had no idea.
