The success of an enterprise depends on teamwork; the strength of an individual is limited.

Diplomacy requires maintaining calmness and rationality, free from emotions and personal biases.

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.

生命中最要紧的事即是彼此。
