My favorite moments? Where it's all going swimmingly, the sun's out and I've got a fire going and a nice snake on the barbecue.

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

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.

The SAS Reserve tends to be made up of former paratroopers and commandos who still want a challenge, but it is open to civilians.

Nobody else is stupid enough to get themselves into the straits that I get into.

Faith is personal if it's to be real.

My faith isn't very churchy, it's a pretty personal, intimate thing and has been a huge source of strength in moments of life and death.
