We must measure success not just in profits, but in impact.
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.
我们利用现有的东西,因为它们有价值
我们思考是为了行动,行动是为了生存。
不要太相信什么正直无私,对任何人都要提高警惕。
