我们生活在一个一切都可以出售的世界，包括我们的灵魂。

我只和自己竞争，不和别人竞争。

如果你是以竞争者为中心的，你必须等到有竞争者在做某事。以客户为中心让你能更有先锋精神。

如果你想成功，就必须愿意做出艰难的决定。

唯有通过形式，才能征服混沌。

I don't believe in pessimism. If something doesn't come up the way you want, forge ahead. If you think it's going to rain, it will.

文明被描述为对一系列挑战的回应结果，而其中最大的挑战始终是气候。

I was working at a financial firm in New York City with a bunch of very smart people， and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park， listened carefully to me， and finally said， "That sounds like a really good idea， but it would be an even better idea for someone who didn't already have a good job." That logic made some sense to me， and he convinced me to think about it for 48 hours before making a final decision. Seen in that light， it really was a difficult choice， but ultimately， I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always be haunted by a decision to not try at all. After much consideration， I took the less safe path to follow my passion， and I'm proud of that choice.
