The designated leader generally demonstrates through their achievements and attitude that they possess qualities that merit them being elevated to a leadership role in their organization. How they go about doing their work and relating to others identifies their special qualities. In this case, they are excellent workers, creative and problem-solvers that do their job without making waves or drawing attention to themselves. They are also responsible and accountable but not necessarily with an agenda that seeks a leadership position.
It is not uncommon for workers with exceptional talent and work behavior to be considered for leadership positions. Still, the people I specifically refer to in this paper are excellent employees because they are good and without expectations that they become leaders. The differences between the exceptional employee who does high-quality work (because it is the job they do) and the employee that seeks to become a leader are considerable. Their intentions are different and eventually seen for what they are.
Those given leadership positions must also be given training in how to use their newfound power and influence. While the excellent employee will view this positively, it might prove difficult for the employee who wants and seeks to become a leader. This, because their reasons for being where they are and their views on newfound power are vastly different.
For the former, it is a job to be done as well as possible and empower those they lead to be as good as they can be.
The person who seeks leadership to have power over those they lead is focused primarily on themselves and their own glory. What they do and how they lead is secondary. These differences are not subtle, nor are their relationships and outcomes.
As for the person committed to being their own boss, their path may not have to do with control, power, or influence. They may choose never to be an employee of an organization. Money may or may not drive them. Power over others may not drive them. Being the best at what one does may or may not drive them. First and foremost, they have decided to be professionally independent, depending on only themselves.
