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.

You only get one chance at life and you have to grab it boldly.

Adventure should be 80 percent 'I think this is manageable,' but it's good to have that last 20 percent where you're right outside your comfort zone. Still safe, but outside your comfort zone.

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

I hang out all the time with kids and young scouts and I never meet kids who don't want adventure.

The rules of survival never change, whether you're in a desert or in an arena.

Life is an adventure that is best lived boldly
