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.

"The best way to predict the future is to create it."

改变不会一夜之间发生，但每一步前进都是朝着正确的方向迈出的一步。

老脑筋就像老马；如果你想保持它们的工作状态，就必须锻炼它们。
