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.

I often ask myself: "What would Theodore Roosevelt do?" One can never know, of course. The ultimate contribution of consequential leaders is often their capacity to reframe issues in novel ways. That said, his leadership engaged, at a foundational level, whether the American "national character" would accept decline and mediocrity, or would go all-in for leadership and excellence. Amid the myriad of otherwise disconnected issues before us, that choice is emerging yet again.

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.

One of the greatest misconceptions about Theodore Roosevelt - in his time and ours - is that he was impetuous.

Theodore Roosevelt regarded leadership as his one gift, the area in which he might be considered to possess genius. He presented his views on leadership throughout his voluminous writings. He intended for future writers to study them with an eye toward action, as he himself had done of historic figures.

My books arose from my own experience, when I sought guidance in practical leadership in my career. In sum, I strive to write the kind of book that I would find valuable in my own life.

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.
