山的故事不是用文字写成的，而是刻在人们脸上的皱纹里。

人は誰でも、自分だけの物語を持っている。

I’m not here to be average, I’m here to be awesome.

强求不得，顺其自然。

The absence is often more powerful than the presence.

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.
