Query: Oil-rich WaitePhillips becomes richer by giving it all away.

This is a fascinating story of Waite Phillips and his dreams of living a cowboy life out west, his bond with twin brother Wiatt, and his life as an oilman, wildcatter and millionare. Most importantly, it is the story of a man with the wisdom to understand that "A man keeps nothing unless he gives it away". His gifts to the Boy Scouts of America, hospitals, universities, and the city of Tulsa stand as a testiment to his wisdom and love of people. I recommend this book more often than any other. It should be required reading for all.
