Interesting - got a recommendation for a book that deals more with his tactics or the ruthless side? I admire people who are ruthless without hurting others, breaking the law, or otherwise being bad people. You can even learn from people who might go too far - I just ordered "Titan" about John Rockefeller from Amazon, along with "Taiko" about 1600's Sengoku Japan. Some ruthless men in those books - I try to understand and internalize the drive while spotting potential Tony Montana style pitfalls in advance.
