The only legitimate form of discipline is self-discipline, having the inner will to do whatever it takes to create a great outcome, no matter how difficult. When you have disciplined people, you don’t need hierarchy. When you have disciplined thought, you don’t need bureaucracy. When you have disciplined action, you don’t need excessive controls. When you combine a culture of discipline with an ethic of entrepreneurship, you create a powerful mixture that correlates with great performance. To build an enduring great organization — whether in the business or social sectors — you need disciplined people who engage in disciplined thought and take disciplined action to produce superior results and make a distinctive impact in the world.
