上帝存在于細(xì)節(jié)之中。

發(fā)憤研究學(xué)問(wèn)，常常忘記吃飯，一旦有所收獲便又高興地忘記了憂(yōu)愁，連自己的漸趨衰老也沒(méi)有感覺(jué)到。

光是建筑的本質(zhì)。沒(méi)有光，就沒(méi)有空間。

Life is like a ten-speed bicycle...Most of us have gears we never use!.

The best way to predict the future is to create it.

And I hope you will come back here to Harvard 30 years from now and reflect on what you have done with your talent and your energy. I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world's deepest inequities…on how well you treated people a world away who have nothing in common with you but their humanity.
