In 2003, I almost died of an intestinal blockage when I was on a mountain in Chile, filming a segment for 'Scientific American Frontiers.'

Here's my Golden Rule for a tarnished age: Be fair with others, but keep after them until they're fair with you.

I was brought up as a Catholic, and I'm no longer a Catholic. I don't talk about my beliefs too much in public probably because I feel very strongly that it's something personal - more than personal, it's private.

Real listening is a willingness to let the other person change you.

For me, I find that even though I've accomplished a few things in my life, looking back on accomplishments doesn't give me a sense of satisfaction.

You have to leave the city of your comfort and go into the wilderness of your intuition. What you'll discover will be wonderful. What you'll discover is yourself.

I found I wasn't asking good enough questions because I assumed I knew something.
