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.

Dwight Eisenhower has been underestimated, which may relate to his advanced age in office, his somewhat uneven communications skills, and his failure to present a forward-looking vision on the rising issue of civil rights.

Woodrow Wilson is reported to have told a Princeton colleague, shortly after the 1912 election, "It would be an irony of fate if my administration had to deal chiefly with foreign problems, for all my preparation has been in domestic matters." In the event, Wilson's early months were marked by substantial domestic legislative accomplishment. Unfortunately, after Europe plunged into the Great War in August 1914, Wilson's leadership was uncertain.

Ronald Reagan was a traditionalist - who purposefully, effectively unleashed innovation and change in himself, in the nation, and in the world. He was a "great communicator" who achieved memorable intimacy with the people everywhere - yet he was often disengaged from his own family.

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.

Effective leaders at a high level tend to be skilled actors. Franklin Roosevelt is said to have to quipped, on being introduced to Orson Welles, that they were the two greatest actors in America. The story may be apocryphal, but the message rings true.

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.
