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.

For me, my training is a key part of my work as so often my life has depended on being able to move fast and haul myself up and out of something fast!

Faith is personal if it's to be real.

I think fire is so critical in the wild. You can cook with it, you can make tools, you can deter a predator, you can dry your clothes and you get that element of morale that matters so much when you're stuck in the middle of nowhere.

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.

A friend once asked me what qualities were needed for SAS. I would say to be self-motivated and resilient; to be calm, yet have the ability to smile when it is grim; to be unflappable, be able to react fast and to have an ‘improvise, adapt and overcome’ mentality.

Are you the sort of person who can turn around when you have nothing left, and find that little bit extra inside you to keep going, or do you sag and wilt with exhaustion? It is a mental game, and it is hard to tell how people will react until they are squeezed.
