The single biggest barrier to effective leadership is, in my view, the leadership industry itself. Instead of telling people the skills and behaviors they need to be effective in getting things done, we tell them almost the opposite - blandishments about how we wish people would be, and how we wish workplaces were. That information is worse than useless as, to the extent people believe it, they often wind up losing their jobs.

People tell me the Netflix series, House of Cards, is sort of like my class come to life. The movie Margin Call portrays the realities of hierarchical relationships and rivalries beautifully, and how people respond when under pressure. Gandhi and Long Walk to Freedom both have the virtue of presenting larger-than-life figures in a more realistic way, showing their flaws and contradictions - their humanity - in a way that is very helpful.

Almost no one as I think most leadership books are a joke. They are, as I note in Leadership BS, frequently based on wishes and hopes rather than reality, on inspiring stories rather than systematic social science, and on "oughts" rather than "is."

Lyndon Johnson (with Abraham Lincoln close behind). Johnson was able to get things done, to read other people, and to adjust his own approach accordingly. One of the reasons he has so fascinated biographer Robert Caro over the years is Johnson's consummate skill in acquiring and using influence.

Lying is common in social life, often done for benign purposes, seldom draws severe sanctions, and many of the most notable leaders, including the late Steve Jobs, were consummate prevaricators. Told with enough persistence and conviction, what was once untrue can become true, in a self-fulfilling prophecy sort of way.

Successful organizations understand the importance of implementation, not just strategy, and, moreover, recognize the crucial role of their people in this process.

Doris Kearns Goodwin's Team of Rivals is instructive in painting a realistic portrayal of Lincoln and his methods for accomplishing his objectives. In fact, many good political biographies are useful in learning about power, strategy, and decision-making.
