Adventure should be 80 percent 'I think this is manageable,' but it's good to have that last 20 percent where you're right outside your comfort zone. Still safe, but outside your comfort zone.

My work is all about adventure and teamwork in some of the most inhospitable jungles, mountains and deserts on the planet. If you aren't able to look after yourself and each other, then people die.

The difference between ordinary and extra-ordinary is so often just simply that little word - extra.

Why is it that the finish line always tends to appear just after the point at which we most want to give up? is it the universe's way of reserving the best for those who can give the most? What I do know, from nature, is that the dawn only appears after the darkest hour.

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.

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

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