The urban tribe is overrated.

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.

There’s no such thing as a mistake in art—only unexpected turns.

仅仅做好事是不够的；必须以正确的方式去做。

预测未来的最好方法就是创造未来。
