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."

California is, in many respects, best understood as a nation-state. In the environmental-energy realm, California possesses far-reaching legal authorities that other states do not.

Theodore Roosevelt is among the most captivating of presidents in our time, but his administration is often underestimated. Roosevelt's successes in domestic and international affairs are so wide-ranging as to appear obvious or inevitable in retrospect.

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.

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.

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.
