Lance Armstrong pushes the envelope in terms of the human experience. You can have a personal best, you can push your own envelope. For Lance, the person pushing him is him. The only person he's competing with, I think, is himself. To push that limit to the next step. There's a lot to learn from him. Lots.

I went to rehab [for alcoholism] in wine country, just to keep my options open.

I was in Iraq, Afghanistan, Djibouti, Bahrain. The first year I went pretty much by myself. Then I went with General [Richard] Myers, head of the Joint Chiefs of Staff. The shows and audiences were amazing. You'll never get a better group of people.

I love kids, but they are a tough audience.

[when asked about what he was most thankful about]: Being alive. After heart surgery, you dig that part. Breath, family and friends are just amazing. Just to have a second shot is pretty great!

You have this idea that you'd better keep working otherwise people will forget. And that was dangerous. And then you realize, no, actually if you take a break people might be more interested in you.

I learned that by being entertaining you make a connection with another person.
