I would give Obama a "C." He gets an "A" for understanding this country's profound problems in education, health care, infrastructure, and economic competitiveness, and for surrounding himself with extremely skilled and knowledgeable people who know what to do. He probably gets an "F," ironically, in his ability to sell these ideas to the American public and to be angry enough, conniving enough, and frankly mean enough to get them implemented and understood.

Advocates of knowledge management as the next big thing have advanced the proposition that what companies need is more intellectual capital. While that is undeniably true, its only partly true. What those advocates are forgetting is that knowledge is only useful if you do something with it.

Many of our students want to do what they have done and that has made them successful thus far in their lives: play by the rules, and do what is expected. But as much social science research and writing by Malcolm Gladwell, among others, make clear, the rules are mostly created by those already in power so obtaining power often entails standing out and breaking rules and social conventions.

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.

Everyone faces defeats, setbacks, reversals of fortune. But just like water wearing away rock, persistence triumphs. Resilience is one of the most important qualities I would look at in trying to predict who is going to be ultimately successful.

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 who don't have as much power as they would like often begin by attributing their difficulties to the environment - competitors, bosses, economic circumstances, and so forth. But in reality people are customarily their own biggest impediment to being as powerful as they would like.
