I don't like expeditions where it is a total lottery whether you live or die. You have to keep those sort of good luck cards for rare occasions!

And if you give your heart to a goal, it will repay you. It's the law of the universe.

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.

I exercise about 40 minutes a day, and I'll run one day and do circuit training the next day. I live in an area where there are brilliant hills and mountains, so I get a good hill run with my dog. At home, I'll do the circuit training with old weights, along with pull-ups in the trees and that sort of stuff.

The difference between ordinary and extra-ordinary is so often just simply that little word - extra. And for me, I had always grown up with the belief that if someone succeeds it is because they are brilliant or talented or just better than me... and the more of these words I heard the smaller I always felt! But the truth is often very different... and for me to learn that ordinary me can achieve something extra-ordinary by giving that little bit extra, when everyone else gives up, meant the world to me and I really clung to it.

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.

One killer exercise that's really great is pull-ups with your legs out level. That's my favourite. It's such functional core strength, and that's why I can climb up trees and down vines.
