我想尽可能站在边缘而不掉下去。在边缘上,你能看到从中心看不到的各种东西。
I want to stand as close to the edge as I can without going over. Out on the edge you see all kinds of things you can't see from the center.

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.
