“We recognize that perhaps our greatest accomplishment—with the exception of the kids we raise—will not come from businesses we've started, but from the help we provide to people and causes around the world. We believe, with the others who have signed this Pledge that we are truly on the cusp of life-changing achievements that will improve our collective quality of life, and have an everlasting impact on generations to come.”
