I always try to buy stocks at a discount to their intrinsic value.

I’m not here to fit into anyone’s box. I’m here to be myself.

We've had three big ideas at Amazon that we've stuck with for 18 years， and they're the reason we're successful:Put the customer first. Invent. And be patient.

材料是建筑的语言。

人性中最深刻的原则是对被欣赏的渴望。

重要的不是目的地，而是旅程。

I’m not perfect, but I try my best every day.
