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.

Success in business comes from understanding people, not just markets.

创新不是选择，而是生存的必须。

我的未完成的过去，从后边缠绕到我身上，使我难于死去，请从它那里释放了我吧。
