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.

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.

The special forces gave me the self-confidence to do some extraordinary things in my life. Climbing Everest then cemented my belief in myself.

And if you give your heart to a goal, it will repay you. It's the law of the universe.

You can't become a decent horseman until you fall off and get up again, a good number of times. There's life in a nutshell.

Being brave isn't the absence of fear. Being brave is having that fear but finding a way through it.

I'm terrified of walking into a room full of people. Sitting down at a dinner table with 15 strangers brings me out in a sweat.
