我经历过的挣扎，承受过的痛苦，都体现在我的音乐中。

最好的领导方式是激励。

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 best way to find out if you can trust somebody is to trust them.
