激励是一种艺术，是让人们去做你想让他们做的事，因为他们自己也想去做。

You are never too old to set another goal or to dream a new dream.

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.

你拥有的最强武器是你的头脑。好好训练它。
