Query: Boastful book with a few barbs for those who crossed him!

Somewhat dull look at a very smart but very vain, and boastful man. He names some of his enemies and others he outsmarted in his business ventures, which seems a bit mean spirited to say the least! Good reading for an insomniac like me. It put me right to sleep!
