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.

Lyndon Johnson (with Abraham Lincoln close behind). Johnson was able to get things done, to read other people, and to adjust his own approach accordingly. One of the reasons he has so fascinated biographer Robert Caro over the years is Johnson's consummate skill in acquiring and using influence.

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.

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.

Everyone faces defeats, setbacks, reversals of fortune. But just like water wearing away rock, persistence triumphs. Resilience is one of the most important qualities I would look at in trying to predict who is going to be ultimately successful.

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.
