Dwight Eisenhower has been underestimated, which may relate to his advanced age in office, his somewhat uneven communications skills, and his failure to present a forward-looking vision on the rising issue of civil rights.

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.

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 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.

William McKinley has surely been underrated - in no small part because he was succeeded by a memorable leader, Theodore Roosevelt.

Ronald Reagan was a traditionalist - who purposefully, effectively unleashed innovation and change in himself, in the nation, and in the world. He was a "great communicator" who achieved memorable intimacy with the people everywhere - yet he was often disengaged from his own family.

I would suggest two approaches to begin the leadership journey in earnest. First would be to ask oneself, in every interaction with others over the course of a single day: How can you best serve this person? Another approach would be to attempt, over the course of a single day, to reframe your declarative statements into questions. The thoughtful use of questions can be transformational. In my experience, most people find these exercises more challenging - and more rewarding - than they would have imagined.
