A good book by the oil revolutionist of the 20th century. As they say "Men should listen to experience" and this book is all about the experience of the second highest taxpayer of the US during the 20's. Though it is not in the book, this is a small poem he wrote:

I was early taught to work as well as play,
My life has been one long, happy holiday;
Full of work and full of play-
I dropped the worry on the way-
And God was good to me everyday.
