If only they could be more like Chuck Feeney.

In February 2011, Feeney became a signatory to The Giving Pledge. In his letter to Bill Gates and Warren Buffett, the founders of The Giving Pledge, Feeney wrote, “I cannot think of a more personally rewarding and appropriate use of wealth than to give while one is living—to personally devote oneself to meaningful efforts to improve the human condition. More importantly, today’s needs are so great and varied that intelligent philanthropic support and positive interventions can have greater value and impact today than if they are delayed when the needs are greater.” He gave away a final $7 million in late 2016, to the same recipient of his first charitable donations, Cornell University. Over the course of his life, he gave away more than $8 billion.
