I've seen extreme bravery from the least likely of people. Life is about the moments when it's all gone wrong. That's when we define ourselves.

Both faith and fear may sail into your harbor, but only allow faith to drop anchor.

I am not fearless. I get scared plenty. But I have also learned how to channel that emotion to sharpen me.

Change the way you use your time, and you change your life.

I've never really had a TV career. I've been a soldier and a climber.

Life has taught me to be very cautious of a man with a dream, especially a man who has teetered on the edge of life. It gives a fire and recklessness inside that is hard to quantify.

The hardest thing about my job isn't the snake bites or the crocodiles, it's being away from my children. I have a really religious satellite phone call every day back to the boys, wherever we are, whatever time zone, to say goodnight.
