Survival requires us to leave our prejudices at home. It's about doing whatever it takes - and ultimately those with the biggest heart will win.

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.

When I'm filming, survival requires movement. You need your energy, and you've got to eat the bad stuff, and survival food is rarely pretty, but you kind of do it. I get in that zone, and I eat the nasty stuff, but I'm not like that when I'm back home.

The rewards of the wild and the rewards of the survivor go to those who can dig deep, and, ultimately, to the guy who can stay alive.

Our fate is determined by how far we are prepared to push ourselves to stay alive - the decisions we make to survive. We must do whatever it takes to endure and make it through alive.

Survival can be summed up in three words - never give up. That's the heart of it really. Just keep trying.
