Business school graduates from the best schools earn large salaries and frequently rise to positions of great power. It would be nice if they used that power to truly make the world a better place - which entails more than just maximizing their own organization's profits and their own economic well-being.

Your most important task as a leader is to teach people how to think and ask the right questions so that the world doesn't go to hell if you take a day off.

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.

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.

As many people know, our job market problems began long before the latest recession. We have faced literally decades with no substantive increase in median wages, and job growth, except in health and government jobs such as education, has been stagnant for a while. People are now expected to travel more and to work at odd hours to coordinate with people all over the world. Simply put, companies have prospered, but for the most part, people have not.

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.

Point at solutions instead of at each other.
