The individual attributes of warmth and competence are often perceived to be negatively correlated. That doesn't mean they actually are, but that's how people perceive the world. So, cruel people, those who gave negative book reviews, for instance, were seen as less likeable but as more intelligent.

Many companies believe incentives, financial incentives, are the answer to every problem or issue. But people are motivated by much more than money. In particular, people like to feel good about themselves and maintain their self-esteem. 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.

We need to reexamine and reassess the purpose of the corporation, and go back to the idea that senior leadership has responsibilities not just to shareholders but also to customers and employees.

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.

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.

My overall recommendation: for decades corporate policy manuals and HR departments have told people they are responsible for their own careers. It's about time people really heeded those warnings.

The best path to power combines two things: 1) a path that not many are taking and 2) something that you are capable and comfortable with doing.
