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.

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.

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.

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.

Woodrow Wilson administration ended in tragedy, with his insistence on governing following his disabling stroke. I suspect President Wilson is often graded on a special curve, because many academic historians identify with him as one of their own.

The unprecedented transparency of our time is a making change by the day. Our era, with transparency and the spread of information, is decentralizing authority and power at a breakneck pace. Those who understand this can break away. Those who attempt to hold back may well be trampled.

There are people all around us whose lives are masterpieces of service. One thinks of parents working two or three jobs to serve their families and community. So, too, many in the military or in nursing or teaching. As the needs are endless, so are the possibilities of service. Now, more than ever, empowered by the Internet, more of us can serve in more ways than ever before in history.
