Just because you are CEO, don't think you have landed. You must continually increase your learning, the way you think, and the way you approach the organization. I've never forgotten that.

The one thing I have learned as a CEO is that leadership at various levels is vastly different. As you move up the organization, the requirements for leading that organization don't grow vertically; they grow exponentially.

The distance between number one & number two is always constant. If you want to improve the organization, you have to improve yourself and the organization gets pulled up with you.

You don't want to negotiate the price of simple things you buy every day.

Focus relentlessly and passionately on the customer.

The question really is, are you improving the world? And you can do that in many models. You can do that in government, you can do that in a nonprofit, and you can do it in commercial enterprise.
