You can't live someone else's expectations in life. It's a recipe for disaster.

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.

I was always brought up to have a cup of tea at halfway up a rock face.

Never depend on those luck moments – they are gifts – but instead always build your own back-up plan.

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

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.
