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.

The stories we don’t tell are the ones that haunt us the most.

释义：做事情必须踏踏实实，不要追求浮华的虚名。
