Ronald Reagan was unusual in being an authentic personality. Unlike many professional actors - and politicians - he was much the same behind the curtain as in front.

Ronald Reagan was notably able to avoid having personal considerations dissuade him from taking decisive actions. This may have arisen in part from his career in motion pictures; it may be related to his being a bit of a loner; it may have related to his focus on those people and principles he sought to serve. What is clear is that this capacity enhanced his effectiveness. It was also a surprise to many people.

Theodore Roosevelt is among the most captivating of presidents in our time, but his administration is often underestimated. Roosevelt's successes in domestic and international affairs are so wide-ranging as to appear obvious or inevitable in retrospect.

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.

My Army reserve service was in the 1990s. It was, more than anything else, an opportunity for me to express gratitude. My understanding of and admiration for the American armed forces is deeper, better informed as a result. I'm among those who believe that military or other citizen service should be an expected part of every American's life.

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.

Curiously, for all the outpourings of scholarship on Theodore Roosevelt, no one had written a book focused directly on his leadership approach, working in large part from his own letters and other writings. That opportunity was open, and I was privileged to step in.
