You're not human if you don't feel fear. But I've learnt to treat fear as an emotion that sharpens me. It's there to give me that edge for what I have to do.

Don't be scared to dream big, and don't be afraid to be close to people. And never give up! It's the tenacious not the talented that win.

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

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.

Christianity is not about religion. It's about faith, about being held, about being forgiven. It's about finding joy and finding home.

I've fallen down crevasses, been bitten by snakes, been knocked unconscious, had various limbs broken and once, a heavy camera came plunging down which very nearly decapitated me.

I try and eat really healthy when I'm home, but I certainly don't eat worms and snakes.
