Some titles come with the assumption of leadership skill: CEO, Director, President, Chair, etc.
Some leaders wield influence in informal, yet powerful ways. Many title-less yet impactful leaders traffic their thinking and behavior through the media of influence.
What a blessing when the influencing comes coupled with the title!
What a complete disaster when the title comes completely devoid of the ability to influence.
If no one is following (or if the following is purely the result of forced compliance) then it's NOT leading.
Leaders are wise to take a reflective and thoughtful look in the mirror each day (both to self-examine and to see if anyone is following).
