Scott Neeson former president of 20th Century Fox International, sold his mansion, Porsche, and yacht and left the industry to establish and personally oversee Cambodian Children's Fund as Executive Director.
I remember watching an interview with him in which he told a story of how a phone call with a celebrity made him devote his life to the CCF.
He was in Cambodia, outside of a Phnom Penh, at a landfill, and he was brought to some sick children dying of typhoid. He was with them when he got an international call from a celebrity that he had asked to do publicity for the foundation, who was angry about how something was wrong with their private jet. The celebrity then told him "Scott, my life was never meant to be this difficult". What the celebrity actually said wasn't mere complaining, it revealed an attitude of extreme self-importance.
