Mark Cuban shows us that it's not enough to play by the rules as they are defined. If you are going to achieve greatness as a startup, you need to find your EDGE...which means you have to outmaneuver your competition before they even engage with you on the competitive battlefield. You have to change the rules to your advantage and not just play by the rules as they are given to you. Never fall into the trap of not anticipating how a giant competitor will try to run you out of business someday...because it will happen every time if your startup matters in the first place.
