I mention this because I think one thing that separates mediocre managers from really good ones is that the good ones understand each employee's strengths and weaknesses and try to help them chart a course for success. That means finding their place on the team and it also means growth. It's to everyone's benefit if, 6 months or a year from now, that employee is a better employee. A manager is in a unique position to coach and mentor, and to create the conditions for growth and encourage it. A self-starter employee will do some of this on their own, but they usually need the manager to participate too by doing stuff like recognizing realistic opportunities for an employee to take on more responsibility and taking a chance by trusting them with it. A lot of managers don't seem to even attempt to do any of this or aren't even aware that it's a thing, and then their team languishes and stagnates and they wonder why they aren't getting anything out of their people.
