I would agree that Buffet is a great business leader, but only with regard to being a brilliant long term investor. However, I believe that the people who who have really shaped our world in recent times have been the entrepreneurs who have been willing to take risks and put themselves on the line to build their ideas and dreams into reality. Much of the new wealth that is being created in the world comes from these entrepreneurs - both modern technology entrepreneurs, and also small-time entrepreneurs in the third world using their own initiative to build wealth through trade and business. Who are your favourite entrepreneurs, and why?
