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.
Don't write your name on sand, waves will wash it away. Don't write your name in sky, wind may blow it away. Write your name in the hearts of people, that's where it will stay.
