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.

成功不是快乐的关键。快乐才是成功的关键。如果你热爱你所做的事，你就会成功。

跑步不是要比别人好，而是要比过去的自己更好。

Every song tells a story.

有时人生最困难的事是知道该跨过哪座桥，烧掉哪座桥。
