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.

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.

I've benefited greatly from studying many effective people from history. Among those who've influenced me the most are Ronald Reagan, Theodore Roosevelt, and Winston Churchill. Each of the three altered history; each was self-created to a great extent; and each was a great student of history and leadership.

Ronald Reagan was unusual in being an authentic personality. Unlike many professional actors - and politicians - he was much the same behind the curtain as in front.

If leadership is, fundamentally, about serving others, then any one person should be able to move between being a "leader" and a "follower."

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.

Everyone knows that Theodore Roosevelt was able to wring so much life out of each day, every hour, every minute. And yet, when one is immersed in a detailed, retrospective review of his life, his intense living, his vigor di vita, is nonetheless breathtaking.
