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.

I've learned that you can't control everything, and sometimes you just have to let go.

人生在世，贵在勤劳。勤劳就不会贫乏。
