改变令人不适，但它是进步的必要条件。

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.

你最大的敌人是你自己的人性——你的不耐烦、你的恐惧、你对认可的渴望。

我不是来讨人喜欢的，我是来做我的工作的。
