The kind of commitment I find among the best performers across virtually every field is a single-minded passion for what they do, an unwavering desire for excellence in the way they think and the way they work. Genuine confidence is what launches you out of bed in the morning, and through your day with a spring in your step.

Greatest danger is not failure, but be successful and not know why.

You need self-control in an out-of-control world.

Good is the enemy of great. And that is one of the key reasons why we have so little that becomes great. We don't have great schools, principally because we have good schools. We don't have great government, principally because we have good government. Few people attain great lives, in large part because it is just so easy to settle for a good life.

In an ironic twist, I now see Good to Great not as a sequel to Built to Last, but more of a prequel. Good to Great is about how to turn a good organization into one that produces sustained great results. Built to Last is about how you take a company with great results and turn it into an enduring great company of iconic stature.

Most people will look back and realize they did not have a great life because it's just so easy to settle for a good life.

The challenge is not just to build a company that can endure; but to build one that is worthy of enduring.
