Nobody wants to end up super rich and famous - but divorced. I'm always clear on that and try to stay on the right side of the line.

I was always brought up to have a cup of tea at halfway up a rock face.

One thing I know for sure: it is only by doing what we fear that we can ever truly learn to be brave.

I hang out all the time with kids and young scouts and I never meet kids who don't want adventure.

I do see a lot of the hard end of ecology, and my feeling is that we live on a super-exciting planet but a super-fragile one.

A friend once asked me what qualities were needed for SAS. I would say to be self-motivated and resilient; to be calm, yet have the ability to smile when it is grim; to be unflappable, be able to react fast and to have an ‘improvise, adapt and overcome’ mentality.

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