That is the key challenge facing management today; change is the only constant.

First and foremost, effective leaders must continuously strive to make themselves smarter and better at making judgments.

What job is worth the enormous psychic cost of following a leader who values loyalty in the narrowest sense.

Leaders learn by leading, and they learn bestby leading in the face of obstacles. As weather shapes mountains, problems shape leaders.

One of the worst mistakes is to do nothing.

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

Charisma is the result of effective leadership, not the other way around.
