我不是光明，我是黑暗。

It is vain to talk of the interest of the community， without understanding what is the interest of the individual.

Sustainability isn't a trend; it's the future of business.

最好的建筑是那些消失在景观中的建筑。

The best leaders are those who listen more than they speak.

The greatest gift you can give someone is your time, because you are giving them a portion of your life that you will never get back.

我是一个乐观主义者。我相信人类智慧的力量能够克服挑战。
