Theodore Roosevelt is of singular interest, because he was, in many evident ways, a self-created figure. He transformed his life into performance art. He intended his life to be an example for others to learn from or even emulate.

Theodore Roosevelt crafted a masterpiece of service. He served people in every aspect of his life. His legacy was transformational, encompassing his family, his nation and the world.

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.

It was a particular pleasure to examine President Ronald Reagan's leadership. I experienced it first-hand, as a member of his administration in several capacities as well as his 1984 reelection campaign staff. The most common misconception is that Reagan was a bystander to his own career.

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.

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.

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.
