Alpha was the best thing I ever did. It helped answer some huge questions and to find a simple empowering faith in my life.

I am not fearless. I get scared plenty. But I have also learned how to channel that emotion to sharpen me.

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.

But the wild is unpredictable, stuff does happen, and it's always when you're least expecting 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.

All my life the only thing I've been good at has been climbing and throwing myself off big things.

A man's pride can be his downfall, and he needs to learn when to turn to others for support and guidance.
