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.

Is your ego small enough, and your backbone strong enough, to raise others up high on your shoulders?

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.
