My first company was MicroSolutions. I worked 20 hours a day. I didn't take a vacation for 7 years. I didn't even take the time to read a fiction book. It was all about work. When I sold it, I promised myself I would never wear a watch and only wear a suit to weddings, funerals and to meet the President.
