One can measure the quality of a leader by their accomplishments. Real leaders produce results. Those who are unable to produce results are not really leading. And yet, sometimes the results of a leader’s actions are not always known. Because sometimes, the best course of action is taken in private, behind the scenes. Not because a great leader must be sneaky or manipulative. On the contrary, the best leaders often act with a disinterest in public credit for their achievements.
The primary goal of a great leader is the greater good of the organization. They are more interested in advancing their team than in their personal achievements. So they unselfishly lead their organizations, giving credit to the entire team when an achievement is known. They know that sometimes an achievement is reached that only they can appreciate.
