I believe that in any initiative, you can't have a flavor of the month. When you believe something is profound in a company, you can not be a logical leader. You have to go to the lunatic fringe. There is no way that logic is what you need to change people.

Management is all about managing in the short term, while developing the plans for the long term.

When it's time to let someone go, do it right. No surprises. No humiliation.

An overburdened, overstretched executive is the best executive, because he or she doesn't have the time to meddle, to deal in trivia, to bother people.

Trust is enormously powerful in a corporation. People won't do their best unless they believe they'll be treated fairly. The only way I know how to create that kind of trust is by laying out your values and then walking the talk. You've got to do what you say you'll do, consistently, over time.

The biggest opportunity for big companies has come by far in the digitization of internal processes.

In order to lead a country or a company, you've got to get everybody on the same page and you've got to be able to have a vision of where you're going.
