Nothing comes without trade-offs. Do you want to spend time with people who like, or with people who might be useful to you? Do you really want to put in the long hours and constant attention required to be successful in your quest for power? Do you really want to be under the microscope on a daily basis, with people commenting on the car you drive, where you live, where you go on vacation, and so forth? There is no way to avoid the price of power. It's up to you to decide if it is worth it, and to change course when it isn't.

Career success depends on people's educational credentials, their length of service (job tenure), unfortunately it is still the case on their race, gender, and similarity to those in power, and of course, on their political skills. Job performance matters, but less than most people think.

We now live in an era of the permanent campaign - all marketing and messaging all the time. We clearly live in an era where the "truth" doesn't matter much - people tell lies about things ranging from the likelihood of "death panels" to the effects of the stimulus on saving this economy from a true calamity. In such a context, Obama himself needs to be "selling" all the time, as does his team, and also be more forceful in advocating their views. He needs to project that he and his ideas will win. And I don't think he has yet done that.

While it is almost certainly true that leaders ought to eat last, the evidence on the ever-widening difference between CEO and average employee pay and the enormous severance packages leaders obtain even as front-line workers see their economic well-being eviscerated makes a mockery of the idea that leaders do anything other than take care of themselves.

Volumes in the series on Lyndon Johnson, including Master of the Senate and The Path Power, describe how Johnson created resources out of nothing and built a substantial power base.

I don't think eliminating the knowing-doing gap depends on the amount of knowledge around. It depends much more on people's attitudes and intentions - do they actually want to turn knowledge into action, or just go through the motions of acting as if they are busy or are accomplishing something.

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.
