This is a great simple, yet strong piece on starting a business. The word passion has become kind of overused and cliched when applied to entrepreneurship. Many successful entrepreneurs have echoed Cuban's thoughts about being "obsessed" with your vision. This reminds me of when I attended last year's CFE trip to New York and heard a biomedical entrepreneur tell us that "you have to want it so bad that you can't see straight." Another good point Mark Cuban makes is the importance of tangible monetization. Anyone can think of a great idea, few can build a real business around it.
