青春美酒并不总是随岁月流逝而日渐清彻，有时它会日渐混浊。
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.
Success is not about the destination, but the journey and the lessons learned along the way.
