"Every word we write is a step towards understanding ourselves and the world around us."

The truth is rarely pure and never simple.

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 most important thing is to have a good heart and a good attitude.

Success is a journey, not a destination.

世界是事实的总体，而不是事物的总体。

I'm not a fucking role model.

Life isn't about finding yourself. Life is about creating yourself.
