All of Robert Caro's biographies are exceptional, in part because of Caro's fundamental ambivalence about power. He sees its necessity and use for getting things done, even as he is often repelled by watching power at close range. His masterpiece on Robert Moses, The Power Broker, describes the evolution of Moses from idealist to pragmatist as he became one of the most powerful figures in the 20th century.

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.

I would give Obama a "C." He gets an "A" for understanding this country's profound problems in education, health care, infrastructure, and economic competitiveness, and for surrounding himself with extremely skilled and knowledgeable people who know what to do. He probably gets an "F," ironically, in his ability to sell these ideas to the American public and to be angry enough, conniving enough, and frankly mean enough to get them implemented and understood.

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.

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.

I am increasingly convinced that people who have power are not necessarily smarter than others. Beyond a certain level of intelligence and level in the hierarchy, everyone is smart. What differentiates people is their political skill and savvy.
