I believe that if you put in the work, the results will come.

I love to think of nature as an unlimited broadcasting station, through which God speaks to us every hour, if we will only tune in.

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.

晏子春秋

最优财政政策要求税收随时间平滑，因为突然的变化会扭曲经济决策。

领导力不是发号施令，而是激励他人成就卓越。

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.
