Great companies foster a productive tension between continuity and change.

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.

In a world of constant change, the fundamentals are more important than ever.

Greatness is not a function of circumstance. Greatness, it turns out, is largely a matter of conscious choice, and discipline.

You can't manufacture passion or "motivate" people to feel passionate. You can only discover what ignites your passion and the passions of those around you.

A company should limit its growth based on its ability to attract enough of the right people.

Good is the enemy of great. And that's one of the key reasons why we have so little that becomes great.
