The drive for progress doesn't wait for the external world to say "It's time to change."

Don't be interesting - be interested.

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.

Good is the enemy of great.

You absolutely must have the discipline not to hire until you find the right people.

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.
