The greatest journeys all start with a single step.

Sometimes an ember is all we need.

I exercise about 40 minutes a day, and I'll run one day and do circuit training the next day. I live in an area where there are brilliant hills and mountains, so I get a good hill run with my dog. At home, I'll do the circuit training with old weights, along with pull-ups in the trees and that sort of stuff.

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 never wanted to do TV. I just did what I was trained to do through the Special Forces, and I've been doing that from a very young age.

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.

Once a job it has begun, do not stop until it's done. Whether it is big or small, do it well or not all.
