HUMILITY. Imitate Jesus and Socrates.

记忆是脆弱的，但文学可以把它从遗忘中拯救出来。

忧愁在我心中沈寂平静，正如黄昏在寂静的林中。

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.

The interplay between local and global phenomena is a recurring theme in number theory.
