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

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. Perhaps, then you might gain that great tranquility that comes from knowing that you've had a hand in creating something of intrinsic excellence that makes a contribution. Indeed, you might even gain that deepest of all satisfactions: knowing that your short time on this earth has been well spent, and that it mattered.

It's more important than ever to define yourself in terms of what you stand for rather than what you make, because what you make is going to become outmoded faster than it has at any time in the past. ...hang on to the idea of who you are as a company, and focus not on what you do, but on what you could do. By being really clear about what you stand for and why you exist, you can see what you could do with a much more open mind. You enhance your ability to adapt to change.

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

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.

Comparison, a great teacher once told me, is the cardinal sin of modern life. It traps us in a game that we can't win. Once we define ourselves in terms of others, we lose the freedom to shape our own lives.

Focusing solely on what you can potentially do better than any other organization is the only path to greatness.
