You have a whole life in the outdoors, you realize you have a sense of responsibility to protect these wild places.

Doing risk sports had taught me another important lesson: never exceed your limits. You push the envelope and you live for those moments when you’re right on the edge, but you don’t go over. You have to be true to yourself; you have to know your strengths and limitations and live within your means. The same is true for a business. The sooner a company tries to be what it is not, the sooner it tries to ‘have it all,’ the sooner it will die.

The whole purpose of climbing something like Everest is to effect some sort of spiritual and physical gain. But if you compromise the process you’re an asshole when you start out and an asshole when you get back.

One thing I did not want to change, even if we got serious, work had to be enjoyable on a daily basis. We all had to come to work on the balls of our feet and go up the stairs two at a time.

It's okay to be eccentric if you're rich; otherwise you're just crazy.

There is a beginning and end to all life - and to all human endeavors. Species evolve and die off. Empires rise, then break apart. Businesses grow, then fold. There are no exceptions. I'm OK with all that. Yet it pains me to bear witness to the sixth great extinction, where we humans are directly responsible for the extirpation of so many wonderful creatures and invaluable indigenous cultures. It saddens me to observe the plight of our own species; we appear to be incapable of solving our problems.

You have to remember this was the '60s, when climbing was dangerous and sex was safe.
