People in great groups have blinders on. Their work is all they see. They value failures as learning opportunities. They are optimistic, not realistic, as they proceed from one challenge and crisis to the next.

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

People vary enormously in how they learn. Some learn through their eyes - by reading but also by responding to all kinds of visual information. Others learn mostly through their ears or touch or other senses.

The capacity for "uncontaminated wonder," ultimately, is what distinguishes the successful from the ordinary, the happily engaged players of whatever era from the chronically disappointed and malcontent. Therein lies a lesson for geeks, geezers, and the sea of people who fall in between.

It is the capacity to develop and improve their skills that distinguishes leaders from followers.

Vision animates, inspires, transforms purpose into action.

Leaders are people who do the right thing; managers are people who do things right.
