物类之起，必有所始。荣辱之来，必象其德。
正所谓“物以类聚，人以群分”，自己处在什么样的圈子里，自己一定有这个圈子的特点。自身的荣辱祸福都是由自己的行为决定的。比如，两堆柴火堆放的样子差不多，但是火星总是容易在干的那一堆里着起火。很多时候我们抱怨别人和不顺心的事，然而往往是自身的问题。
我们拥有的最有价值的资源不是石油或天然气，而是人类的聪明才智。
We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that, because we believe -- and we have to take this as an article of faith -- that by keeping our prices very, very low, we earn trust with customers over time, and that that actually does maximize free cash flow over the long term.

最伟大的故事是那些挑战我们信念的故事。
