We choose to believe that the granite is alive. If life is movement, then rock - with its atoms flying around like stars in cosmos - is alive.

My favorite quote about entrepreneurship is that to understand an entrepreneur, you should study a juvenile delinquent. They're both saying: "This sucks and I'm going to do it another way." You have to want to break the rules and prove that your way works.

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.

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.

Just why is Yosemite climbing so different ? Why does it have techniques, ethics and equipment all of its own ? The basic reason lies in the rock itself. Nowhere else in the world is the rock so exfoliated, so glacier-polished and so devoid of handholds. All of the climbing lines follow vertical crack systems. Every piton crack, every handhold is a vertical one. Special techniques and equipment have evolved through absolute necessity.
