...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.

I say the last 10 percent of the way to perfection takes so much of your life that it isn't worth the effort. This overzealous attitude is what creates religious fanatics, body Nazis, and athletes who are exceedingly dull to converse with.

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.

The more I make the more I can give away.

Hire extremely independent, intelligent, and passionate people, not necessarily "experts." Maybe three or four of my employees have MBAs, and those guys aren't necessarily at the top of the food chain.

Mainly, my job is to be on the outside and bring ideas into the company and forge change. Most people hate change—it’s threatening. I thrive on it.

The solution may be for a lot of the world's problems is to turn around and take a forward step. You can't just keep trying to make a flawed system work.
