The hardest thing in the world is to simplify your life; it’s so easy to make it complex.

Climbing for speed records will probably become more popular, a mania which has just begun. Climbers climb not just to see how fast and efficiently they can do it, but far worse, to see how much faster and more efficiently they are than a party which did the same climb a few days before. The climb becomes secondary, no more important than a racetrack. Man is pitted against man.

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.

...there's no such thing as sustainability. There are just levels of it. It's a process, not a real goal. All you can do is work toward it. There's no such thing as any sustainable economy. The only thing I know that's even close to sustainable economic activity would be organic farming on a very small scale or hunting and gathering on a very small scale. And manufacturing, you end up with way more waste than you end up with finished product. It's totally unsustainable. It's just the way it is.

It's not an adventure until something goes wrong.

Evil doesn’t have to be an overt act; it can be merely the absence of good. If you have the ability, the resources, and the opportunity to do good and you do nothing, that can be evil.

Nature doesn't like empires. It doesn't like accumulation in one place, it doesn't like monoculture. It's always trying to make diverse species. It wants to spread everything out. And we're constantly trying to hold everything in.
