Good-to-great companies set their goals and strategies based on understanding; comparison companies set their goals and strategies based on bravado.

A culture of discipline is not a principle of business, it is a principle of greatness.

Those who build and perpetuate mediocrity...are motivated more by the fear of being left behind.

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

Those who turn good organizations into great organizations are motivated by a deep creative urge and an inner compulsion for sheer unadulterated excellence for its own sake.

Discipline should amplify creativity rather than stifle it.

It's what you do before you are in trouble, so that you can be strong when people most need you.
