I began my career in communications and had the privilege of working with senior leaders in a variety of different business sectors. Eventually I decided that rather than helping them develop messages I wanted to help shape lives, that is through teaching, coaching and writing.

Purpose needs to be nurtured. It gains resolve when faced with adversity. The ability to overcome obstacles and challenges is daunting but when accomplished gives us a great feeling of achievement. At the same time we need to nurture purpose by exposing ourselves to new opportunities. We need to learn continuously and we need to teach what we learn to others. Such things like that, and many more, help shape and develop the sense of a leader's purpose so that he or she can provide greater service to the organization.

From the hindsight of history George Washington seems larger than life, more statuesque than man. Too bad! Washington's greatness as a leader was courage under fire and persistence in the face of obstacles. Yet even he at times doubted himself. But he put those doubts aside and forged ahead, convinced of his noble purpose.

Leaders do not motivate per se. They create conditions for people to motivate themselves. They do it by communicating clearly, setting clear expectations, following through and recognizing performance.

Leadership is the behavior each of us exerts when we take responsibility for our actions and their consequences.

Leaders instill purpose through their words and their actions. Their communications demonstrate a commitment to vision and mission, but their behaviors underscore its real importance. What a leader does is far more important than what he or she says. People want to see action and help achieve results.

The words a leader speaks are important, of course. But how they're delivered can make all the difference, especially in tough times.
