The main task in life is simply this: to identify and separate matters so that I can say clearly to myself which are externals not under my control, and which have to do with the choices I actually control.

The act of writing is an act of optimism. You would not take the trouble to do it if you felt it didn't matter.

The future of drones is open and shared.

最好的领导者是那些最热衷于让比自己更聪明的人围绕在自己身边的人。

Old paint on canvas, as it ages, sometimes becomes transparent. When that happens it is possible, in some pictures, to see the original lines: a tree will show through a woman's dress, a child makes way for a dog, a large boat is no longer on an open sea. That is called pentimento because the painter 'repented,' changed his mind. Perhaps it would be as well to say that the old conception, replaced by a later choice, is a way of seeing and then seeing again.

最好的决策来自于同时倾听数据和人的声音。

"The word 'home' always sounds like a lie to me."

沉默比言语说得更多，但必须懂得倾听。

我们必须始终质疑我们的假设，并愿意根据新的证据修正我们的理解。
