“I have long made public my commitment to devote the greater part of my personal wealth to philanthropy. I believe it is my duty to do so and to do it in a way that makes a real difference to lives and to our world.

For me, it is not the size of investment that is the important yardstick, but the size of the return as measured in terms of lives saved or supported. Smart philanthropy is measured by how much good we do for how many people: how many lives did we change, how many children did we educate, how many jobs did we provide?

Over the long term, I want the people and organizations we help to make a sustained difference to the world. I hope that the work of my foundation will continue into the future and strive to address some of the most critical needs of our communities and our planet. Together, we will work to find new solutions to old problems.”
