The more we are committed to believing that something is true, the less likely we are to believe that its opposite is true, even in the face of clear evidence that shows we are wrong.

To help others develop, start with yourself! When the boss acts like a little god and tells everyone else they need to improve, that behavior can be copied at every level of management. Every level then points out how the level below it needs to change. The end result: No one gets much better.

Successful people become great leaders when they learn to shift the focus from themselves to others.

Never confuse acquiring degrees with wisdom.

The major challenge of most executives is not understanding the practice of leadership - it is practicing their understanding of leadership.

People will do something—including changing their behavior—only if it can be demonstrated that doing so is in their own best interests as defined by their own values.

If you aren't opening doors for people, you are closing them!
