All great leaders constantly seek new information and new ways of thinking.

In order to serve its purpose, a vision has to be a shared vision.

Understand the "Pygmalion Effect": Leaders should always expect the very best of those around them. They know that people can change and grow.

The leaders I met, whatever walk of life they were from, whatever institutions they were presiding over, always referred back to the same failure something that happened to them that was personally difficult, even traumatic, something that made them feel that desperate sense of hitting bottom-as something they thought was almost a necessity. It's as if at that moment the iron entered their soul; that moment created the resilience that leaders need.

Great groups deliver great results. And for everyone involved in a great group, great work is its own reward.

Listening to the inner voice - trusting the inner voice - is one of the most important lessons of leadership.

While great leaders may be as rare as great runners, great actors, or great painters, everyone has leadership potential, just as everyone has some ability at running, acting, and painting.
