The single most significant change has been the globalization of labor markets. Product markets - trade in goods - have been globalizing for years. But now, with the reduction in communication expenses and the building of all sorts of IT infrastructure, essentially any job can be done almost anywhere.

Doris Kearns Goodwin's Team of Rivals is instructive in painting a realistic portrayal of Lincoln and his methods for accomplishing his objectives. In fact, many good political biographies are useful in learning about power, strategy, and decision-making.

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.

Being memorable equals getting picked.

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.

The single biggest barrier to effective leadership is, in my view, the leadership industry itself. Instead of telling people the skills and behaviors they need to be effective in getting things done, we tell them almost the opposite - blandishments about how we wish people would be, and how we wish workplaces were. That information is worse than useless as, to the extent people believe it, they often wind up losing their jobs.

Many of our students want to do what they have done and that has made them successful thus far in their lives: play by the rules, and do what is expected. But as much social science research and writing by Malcolm Gladwell, among others, make clear, the rules are mostly created by those already in power so obtaining power often entails standing out and breaking rules and social conventions.
