我们以为我们拥有答案，其实是我们问错了问题。

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.

改变你的思想，你就改变了你的世界。

追求真实的东西，不是追求人们想要的东西。
