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.

过去的33年里，我每天早晨都会看着镜子问自己：“如果今天是我生命中的最后一天，我会想做今天将要做的事吗？”每当答案连续很多天都是“否”时，我知道我需要改变一些事情。

每一天都是成长和学习的新机会。

生活是不公平的，要去适应它。
