In any branding strategy, you need to figure out what is the image you want to project. Then behave accordingly. And above all, cultivate the media and those who will help you burnish your reputation.

To paraphrase the late management thinker and writer, Peter Drucker, thinking is hard work, which is why so few people (including actually senior managers) do it. Once there is some "conventional," seemingly-reasonable story, people just accept it and don't ask, "is this actually true? Is it consistent with the data?" And this extends to the highest reaches of organizational life.

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.

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.

People, to maintain their self-esteem, tend to believe they are above average on all positive qualities - height, income, intelligence, sense of humor, negotiating ability, you name it.

And then act on that knowledge to build the abilities they need to be more successful.

If companies spent more time working on people's feelings of self-worth, they wouldn't have to try, often unsuccessfully, to bribe people to do work.

You are more likely to acquire power by narrowing your focus and applying your energies, like the sun's rays, to a limited range of activities in a small number of domains.
