Leaders are creatures of their environment, but unlike most creatures, they are also movers of it. As movers of and within the organization, they push it forward, at the same time shaping it as much as it shapes them.

All leaders must be good communicators. But let's be clear, communications is not the same as oratory. Let me give you an example. General George C. Marshall was an exemplary public servant and military officer. He helped mobilize our nation for the Second World War and helped lay the foundation for peace as Secretary of State. He communicated through words, but more loudly through his actions.

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.

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.

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.

Heroism is not blind courage: it is selfless action. it is knowing the odds are stacked against you, but feeling that you must do what you do for the good of others.

Communication comes with practice. As a leader you must speak the truth; listen for understanding; and learn from what you hear and do not hear.
