滚动的弹丸，掉落到凹陷之处，便不再滚动了；流传的谣言，到智慧的人那里，便不再流传了。

难道你看不出一个充满痛苦与烦恼的世界对于磨练智慧、造就灵魂是多么必要吗？

Every day is a new opportunity to change your life.

I'm not a star in my own eyes. I'm just a person.

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.

永远不要低估坚持的力量。大多数人放弃得太早。
