For a truly great company, the Big Thing is never any specific line of business or product or idea or invention. The Big Thing is your underlying fly… - Jim Collins

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.

It is the lesson from the mistake that makes it valuable, not the mistake itself.

Contrary finding: The best leaders we studied did not have a visionary ability to predict the future. They observed what worked, figured out why it worked, and built upon proven foundations. They were not more risk taking, more bold, more visionary, and more creative than the comparisons. They were more disciplined, more empirical, and more paranoid. ………. Entrenched myth: A threat filled world favors the speedy; you’re either the quick or the dead. Contrary finding: The idea that leading in a “fast world” always requires “fast decisions” and “fast action” — and that we should embrace an overall ethos of “Fast! Fast! Fast!” — is a good way to get killed. 10X leaders figure out when to go fast, and when not to. Entrenched myth: Radical change on the outside requires radical change on the inside. Contrary finding: The 10X cases changed less in reaction to their changing world than the comparison cases. Just because your environment is rocked by dramatic change does not mean that you should inflict radical change upon yourself.
