The past is always tense, the future perfect.

2012年：贝索斯致股东信《长远思考才能做到不可能的事情》

爱情里面要是搀杂了和它本身无关的算计，那就不是真的爱情。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

In the end， we will remember not the words of our enemies， but the silence of our friends.

未来取决于你今天做什么。
