舞台是一个神奇的地方，在那里我可以完全自由。

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.

孤独是人类的处境，再多的技术也无法改变这一点。

In the end, it is not the years in your life that count, but the life in your years.

Dream big, work hard, and never let anyone dim your sparkle.

当我们在没有危险的情况下征服时，我们的胜利就没有荣耀。

我不害怕为我的信仰挺身而出。
