Great strategy, not executed, can't possibly have any effect on performance because it doesn't actually affect anything. It's like planning for a successful surgery to remove a tumor. If no one picks up the knife and actually operates effectively, the diseases will persist.

People, to maintain their self-esteem, tend to believe they are above average on all positive qualities - height, income, intelligence, sense of humor, negotiating ability, you name it. The problem is that if we are going to really build our skills, we need to know which skills are most deficient. So, I advise people to find confidantes to tell them the truth. And then act on that knowledge to build the abilities they need to be more successful.

People clearly want to believe that the world is a just and fair place. It provides them a sense of control and makes them psychologically comfortable. But believing that the world is a just and fair place causes people to not do enough to take care of themselves and to be unprepared for when it isn't so nice. So, people need to understand their tendencies to see the world as just and fair and then be realistic about the actual conditions in which they find themselves.

Successful organizations understand the importance of implementation, not just strategy, and, moreover, recognize the crucial role of their people in this process.

Being memorable equals getting picked.

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.

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.
