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.

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.

You can't be normal and expect abnormal returns.

Take care of your customers, and you will have a successful business. Don't, and you won't. The airlines need to figure this out - soon.

To paraphrase the late management thinker and writer, Peter Drucker, thinking is hard work, which is why so few people (including actually senior managers) do it. Once there is some "conventional," seemingly-reasonable story, people just accept it and don't ask, "is this actually true? Is it consistent with the data?" And this extends to the highest reaches of organizational life.

Part of strategy is figuring out what you're good at, figuring out what you're not good at, and then getting yourself in position to succeed by doing mostly what you have a competitive advantage doing.

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.
