Legal training has been quite useful in developing critical thinking. Whether one attains it in mathematics, philosophy or law, an analytic grounding can add great value in defining and confronting complex problems, or laying out a path to implement a vision.

Often, in a given project team or network, one sees leadership roles shifting among various members at various times. Attempts to fit these into traditional views of "leader" and "follower" don't quite work. It's more like Twitter: the "leader" has "followers" - but the "followers" are empowered to alter the relationship unilaterally, and the "leader" must continually earn the consent of the "followers."

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.

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.

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.

When Americans decry our politicians, we must remember that ultimately, politicians reflect us. When we demand more than mediocrity - and the passing comforts it bestows - we will certainly attain it. One hopes and prays it doesn't take an historic crisis for us to demand and reward excellence in public service.

Many people have a very hard time truly believing that doing the right thing by others, striving to serve them to the greatest extent, can actually be a competitive advantage.
