Arguably there's no school for any high position of leadership. That said, Theodore Roosevelt was remarkably well prepared for the presidency. He had held executive positions in the military, in local government, in the federal government.

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.

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.

President-elect John F.Kennedy said to Robert McNamara that there's no school for presidents, or, for that matter, for secretaries of defense.

Many people become self-conscious when they communicate. Whether it's writing or speaking, they are consumed by anxiety. Self-consciousness is an impediment to what is required to serve an audience effectively. One's goal must be to achieve audience consciousness. To put oneself in their place, to recognize that the value of any communication arises from how it is received by them, not by what it means to the author. Rather than learning a multiplicity of rules for speaking, for example, I would suggest that a focus on serving one's audience will simplify and clarify everything.

Ronald Reagan memorably combined intimacy with distance.
