I've watched this video twice now, and I'll probably watch it again. I keep picking up on new things each time. I have to say, this is the most succinct presentation on how to get in the creative mode I've ever seen. And it goes without saying that John Cleese comes off showing his complete understanding of this science-backed thesis in a captivating way. Just thinking about the way he designed the talk to include humor, timing, confidence, intuition and science makes me want to find more videos of him doing this kind of thing so I can study them.
