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.

我不需要完美。我只需要足够好。

所以君子努力做事就会日渐强大，安于嗜欲就日渐苟且，恭敬庄重就日益繁盛。
