What you get by achieving your goals is not as important as what you become by achieving your goals. At your funeral people will not recall what you did； they will only remember how you made them feel.

I don’t let fear stop me, I let it push me.

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.
