John Cleese on How to Be Creative
Very interesting video!
Things learned:
Creativity has nothing to do with intelligence, as it is a mode of behavior. Creativity never happens when you are in a "closed," stressful and concentrating mode. It happens when you are in an "open," relaxed and playful mode. It requires space, time, more time, confidence, and humor.

And there's a lot of lightbulb jokes.

So what do you do to get your creative juices flowing?
