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

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.

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.

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

Good leaders are focused, directive, and inspiring... in other words, purposeful. People want to look up to leaders, not because they think they are better than us, but because good leaders provide us with a sense of purpose that inspires us to do better.

Purposeful organizations develop the next generation, not simply the next leader. My friend Marshall Goldsmith, bestselling author and leading executive coach, does not like the term succession planning. Better to say, "succession development." That means you are focusing on multiple managers and grooming them to lead.

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.
