There is little faith involved in setting out on a journey where the destination is certain and every step in between has been mapped in detail. Bravery, trust, is about leaving camp in the dark, when we do not know the route ahead and cannot be certain we will ever return.

A wise man knows; learn from others, never get complacent and know where the classic old dangers come from.

I always had a really natural faith as a kid. Where I knew God existed and it felt very free and pretty wild and natural, and it wasn't religious.

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.

There's no magic to running far or climbing Everest. Endurance is mental strength. It's all about heart.

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.

Accidents on big mountains happen when people's ambitions cloud their good judgment. Good climbing is about climbing with heart and with instinct, not ambition and pride.
