All my life the only thing I've been good at has been climbing and throwing myself off big things.

Survival is not about being fearless. It's about making a decision, getting on and doing it, because I want to see my kids again, or whatever the reason might be.

One thing I know for sure: it is only by doing what we fear that we can ever truly learn to be brave.

The lesson is, the rewards in life don't always go to the biggest, or the bravest, or the smartest. The rewards go to the dogged; and when your going though hell, to the person who just keeps going.

As for my diet, I try to eat lean, clean and healthy - nothing too surprising. And I avoid too much meat or dairy because they slow you down.

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.

My best life lessons and education didn't come from a classroom - they've come from the wild. How you act in the big moments, the ones that challenge you, scare you, tempt you, and force you to make the right decisions, is what defines you.
