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.

Leaders who lead purposeful organizations are those who put people first. No, it's not a cliché when they actually do it. It means they set clear expectations, provide adequate resources, coach for success, and evaluate for results.

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.

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.

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.

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.
