With respect to trust, people tell me that it is essential for organizational functioning. Maybe, but most surveys of trust find that trust in leaders is low and nonetheless, organizations role along quite nicely.

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.

Those who have power a) understand that the world is not always a just and fair place and accept that fact, b) understand the bases and strategies for acquiring power, and c) take actions consistent with their knowledge in a skillful way. Skill at anything requires practice, and power skills are no different.

Doing the right thing is important, which is where strategy comes in. But doing that thing well—execution—is what sets companies apart. After all, every football play is designed to go for a huge gain. The reason it doesn’t is because of execution—people drop balls, miss blocks, go to the wrong place, and so forth. So, success depends on execution—on the ability to get things done.

Today, if the CEO thinks it's a good idea, it's done everywhere; if the CEO thinks it's a bad idea, it's done nowhere. We ought to be more agnostic and open to learning things that we didn't expect - and the only way to do that is to try things and be open-minded about how well they are working. And third, evidence-based management involves reading and learning - just like doctors do - and to do so not just in school but afterward, as well.

One way to feel good about oneself is to not fail. The easiest way to not fail is to not try in the first place. So, I see lots of people give up before they start. That way they don't have to face uncomfortable failures. They can sort of "remain on the sideline while the game is going on." While this may make people feel good about themselves, it won't get them any power or success. As any successful salesperson will tell you, if you haven't been rejected, you haven't tried enough with enough people.

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.
