I did a dance sequence in my second short film, which was my best short film, called 'Hairway to the Stars,' and I think Chris Wink, the founder of Blue Man Group, was in that. It's a black-and-white dance sequence. We were Glorious Food waiters together.

That's what takes people out of the fight half the time. They get hit and half the reaction is your ego is saying, 'I cannot believe that person just lit me up - how humiliating.

The whole trick is to make it feel like you're spying on real people's lives as they get through the day. When I'm writing, I have to trick myself as a writer. If I consciously say, 'I'm writing,' I feel all this pressure and somehow it doesn't feel as real as when it doesn't seem to count as much.

I think any spiritual experience that's worthwhile is not about ego and it will humble you in some way. And also, a Zen monk once said to me, 'If you're not laughing, then you're not getting it.'

That's the most beautiful thing that I like about boxing: you can take a punch. The biggest thing about taking a punch is your ego reacts and there's no better spiritual lesson than trying to not pay attention to your ego's reaction.
