Effective leadership relationships at a high level include the insertion of a degree of distance from those being served. That may be part of what President Ronald Reagan referred to when he mused that he didn't see how anyone could be president who wasn't an actor.

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

One wonders if Lyndon Johnson and Richard Nixon's administrations may come to be viewed, in the future, as having been underestimated in some respects. To be sure, each ended in failure. Nonetheless, Johnson's accomplishments in civil rights and immigration legislation, and Nixon's in respect to relations with China, may loom larger with the passage of time.

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.

Some critics have suggested that Ronald Reagan succeeded in a series of careers, ultimately as a two-term president of the United States, by a series of fortunate accidents. Such a criticism is not backed by the evidence. It is true, though, that Reagan's approach to work and life was not conventional.

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.

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.
