I’ve never been a natural, all I do is try, try, try.

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 greatest happiness of life is the conviction that we are loved; loved for ourselves, or rather, loved in spite of ourselves.

我不后悔我做过的事，我后悔的是有机会时没有做的事。

我经常需要独处。如果我能从周六晚上到周一早上独自待在我的公寓里，我会非常高兴。这就是我如何给自己充电的。
