Wal-Mart, with its legendary focus on customer value in terms of price, is innovating in sustainability. Now, we're beginning to see the mirror image, a convergence, as the not-for-profit sector is beginning to serve more effectively by applying private sector accountability and efficiencies to social needs. This reflects a rising recognition that to serve others best requires more than good intentions; it mandates a focus on real-world results. Bill Gates and Warren Buffett are among the most conspicuous advocates and representatives of this transformation.

Presidential leadership is best evaluated not on the basis of one's agreement with the policies, but on their effectiveness in using their powers to transform the nation and our understanding of ourselves.

Theodore Roosevelt crafted a masterpiece of service. He served people in every aspect of his life. His legacy was transformational, encompassing his family, his nation and the world.

I've benefited greatly from studying many effective people from history. Among those who've influenced me the most are Ronald Reagan, Theodore Roosevelt, and Winston Churchill. Each of the three altered history; each was self-created to a great extent; and each was a great student of history and leadership.

I often encountered books by academics and others who had not actually done what they had written about. They tend to create artificial simplicity; their prose doesn't have the vigor of "lived words." On the other hand, many practitioners lack the context or introspection to make their experiences and understandings transferable - and, in our time, many don't actually write the books they "author." My ideal is to unify theory and practice.

Everyone knows that Theodore Roosevelt was able to wring so much life out of each day, every hour, every minute. And yet, when one is immersed in a detailed, retrospective review of his life, his intense living, his vigor di vita, is nonetheless breathtaking.
