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.

A visionary company doesn't simply balance between idealism and profitability: it seeks to be highly idealistic and highly profitable. A visionary company doesn't simply balance between preserving a tightly held core ideology and stimulating vigorous change and movement; it does both to an extreme.

For, in the end, it is impossible to have a great life unless it is a meaningful life. And it is very difficult to have a meaningful life without meaningful work.

Smart people instinctively understand the dangers of entrusting our future to self-serving leaders who use our institutions, whether in the corporate or social sectors, to advance their own interests.

All companies have a culture, some companies have discipline, but few companies have a culture of discipline. 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 get the magical alchemy of great performance.

The most effective leaders of companies in transition are the quiet, unassuming people whose inner wiring is such that the worst circumstances bring out their best. They're unflappable, they're ready to die if they have to. But you can trust that, when bad things are happening, they will become clearheaded and focused.

Good is the enemy of great.. The vast majority of good companies remain just that - good, but not great.
