I always love working with teachers. Like every profession, there are good teachers and bad teachers, but I have learned a lot over the years about leadership from having teachers in my leadership development programs. In Oprah’s final show, she introduced and praised her grade four teacher, an early “liberator” who made her feel valued. Think about your own teachers. There are those who just meet the curriculum requirements and help you get into the next grade, while others inspire you, build your character, and mentor you to be a better person, not just a better student. And think about the bosses you’ve had. Some merely help you get your work done, some get in your way, but some change your life. Some help you be a better employee, while others help you be a better person.

How is it that some teachers are merely teachers, but others are leaders, mentors, and life-changers? And how is it that some bosses are merely bosses, while others influence and build your moral fiber, model and teach new attitudes and behaviors, and create a constructive legacy for future generations? It is this distinction that makes a “mentor leader.”

While there are many leadership practices that amplify one’s impact on others, “mentor leaders” possess three qualities of leadership that exemplify their presence:

1) Leaders who make a difference are authentic. They are human, and humble, and present. They also aren’t perfect or attempt to create an illusion of perfection. To impact others, you can’t be phony. People will see right through it. By being who they are, they create a space where others are inspired to also be authentic. Authentic people love what they do and are open to learning about themselves. They are inspired by a purpose and a passion and as a result, they inspire others.

2) Leaders who make a difference are accountable. They can be counted on and don’t make promises they aren’t prepared to keep. They create a place where blame is viewed as a waste of time. They have high standards, both for themselves and those around them. It’s inspiring to be around people you can count on. You aren’t a leader until someone says you are, and you won’t earn the credibility to influence and be trusted if people can’t count on you.

3) Leaders who make a difference care. They care about their work and they care about the people around them. They understand that leading is largely a matter of caring about people, not manipulating or controlling them. Leaders who care measure their success by the trust they build and the value they bring to the lives of others. They are committed to serve. Mentor leaders know that their work is a means to a higher end and put people above products and processes. It’s about changing lives.

Great leadership goes well beyond merely “getting the job done,” and cannot be reduced to technique or position or power. Great leadership inspires others and comes from the strength of one’s identity and integrity – their presence. When teachers possess this presence and inspire it in their students, we are truly fortunate to have them in our lives. The same goes for the leaders in our life and in our work who can help us reach unimaginable potential.
