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.

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.

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.

Witness Donald Trump's current presidential campaign. So first people need to find the white spaces, the unexploited or underexploited niches where there is less competition and more opportunity.

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.

People who don't have as much power as they would like often begin by attributing their difficulties to the environment - competitors, bosses, economic circumstances, and so forth. But in reality people are customarily their own biggest impediment to being as powerful as they would like.

Point at solutions instead of at each other.
