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

If great teams don't have an "enemy," they create one for themselves because, as former Coca-Cola CEO Roberto Goizueta pointed out, "you can't have a war without one."

Effective leaders make a full commitment to be a learner, to keep increasing and nourishing their knowledge and wisdom.

Leaders wonder about everything, want to learn as much as they can, are willing to take risks, experiment, try new things. They do not worry about failure but embrace errors, knowing they will learn from them.

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

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.
