Life has taught me to be very cautious of a man with a dream, especially a man who has teetered on the edge of life. It gives a fire and recklessness inside that is hard to quantify.

You're not human if you don't feel fear. But I've learnt to treat fear as an emotion that sharpens me. It's there to give me that edge for what I have to do.

As a young boy, scouting gave me a confidence and camaraderie that is hard to find in modern life.

Life's full of lots of dream-stealers always telling you you need to do something more sensible. I think it doesn't matter what your dream is, just fight the dream-stealers and hold onto it.

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.

Being Iraqi taught me to be very cautious.
