I tell you what I love - and I think you get better as you get older - when you're younger and you don't know what you don't know, you tend to talk more about what you think you know. You shut out the opportunity to learn what you don't know.

I'm not saying that you shouldn't go to college or you shouldn't finish your degree, but sometimes people have a very clear vision about what they want to do, and they just want to get on with it.

Schools often box kids into predefined categories. But we don't know what amazing ideas, inventions, cures, and contributions all these youths really have.

People ask me what the most important thing to take on the race is, and I always say it's a sense of humor. If you've got nothing but a sense of humor, you will survive.

The world is waiting for you. Good luck. Travel safe. Go!

I love the underdog stories. I love people who refuse to give up.

Inevitably you're going to be delayed somewhere. Always have a book. Always have a movie. Always have a notebook. And then always have a sense of humour.
