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.

做大事和做小事的难易程度是一样的。所以要选择一个值得追求的宏伟目标，让回报与你的努力相匹配。

To be alive is to be mortal. To be alive is to be, from moment to moment, a survivor.
