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.

真相很少纯粹，也绝不简单。

The real problem is not whether machines think but whether men do.

让我们别把自己看得太过重要，没有人可以垄断智慧。

简单是设计中最极致的复杂。
