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.

Authenticity seems like sort of a joke. Actually I believe it was the late comedian George Burns who said, "if you can fake sincerity, you've got it made." People cannot be invariant across situations and roles and, moreover, leaders need to be true not to themselves, but to what others want, need, and expect from them.

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

I decided to write Leadership BS because I was irritated by the hypocrisy in the leadership literature and the fact that many of the people writing leadership books exhibited behavior that was precisely the opposite of what they advocated and also what they claimed they did. Stories did not seem to be a good foundation on which to build a science of leadership.

Volumes in the series on Lyndon Johnson, including Master of the Senate and The Path Power, describe how Johnson created resources out of nothing and built a substantial power base.

While it is almost certainly true that leaders ought to eat last, the evidence on the ever-widening difference between CEO and average employee pay and the enormous severance packages leaders obtain even as front-line workers see their economic well-being eviscerated makes a mockery of the idea that leaders do anything other than take care of themselves.

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.
