I live for the moment. I'm basically a Buddhist-type person. I'm just here right now, and I don't think about what's going to happen a hundred years from now. I try to concentrate on what's going on right now. But I'm really trying to run this company like it is going to be here a hundred years from now. That's what's important.

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.

Most of the damage we cause to the planet is the result of our own ignorance.

We're a part of nature. As we destroy nature, we destroy ourselves. It's a selfish thing to want to protect nature.

You can solo-climb Everest without using oxygen or you can pay guides and Sherpas to carry your loads, put ladders across crevasses, lay in 6,000 feet of fixed ropes, and have one Sherpa pulling you and another pushing you. ... The goal of climbing big, dangerous mountains should be to attain some sort of spiritual and personal growth, but this won't happen if you compromise away the entire process.

Is climbing, as a passion and as a sport, better off now than it was in the past? We can do harder climbs now in faster times - techniques are more refined and equipement more sophisticated - but are we really any better off?

Traveling is my form of self-education. Every stream I fish now is not as good as it used to be. Traveling is my form of self-education. Every stream I fish now is not as good as it used to be. If you keep your eyes open as you travel around, you realize we are destroying this planet.
