可持续发展不是一种选择，而是我们对后代的责任。

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.

Great leaders are willing to make the tough decisions that others avoid.

I’m a fighter, and I believe in standing up for what’s right.

你不能双手都戴着接球手套度过一生。你需要能够回馈些什么。

可持续性不是一种选择，而是长期成功的必要条件。
