The best way to make your dreams come true is to wake up.

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 details are not the details; they make the design.

"The best decisions are often made by a group of people who are not afraid to challenge each other's ideas."

How wonderful that we have met with a paradox. Now we have some hope of making progress.
