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.

I'm terrified of walking into a room full of people. Sitting down at a dinner table with 15 strangers brings me out in a sweat.

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

I am not fearless. I get scared plenty. But I have also learned how to channel that emotion to sharpen me.

Once a job it has begun, do not stop until it's done. Whether it is big or small, do it well or not all.
