Define a Manager?

Answer 1

Your question should be to "define a good manager vs. a bad manager." Or a "manager with talent vs. a manager with little or no talent." Or a "manager who knows what he is doing and knows the grave responsibility he/she has in managing many human lives vs. a manager who steps over the dead bodies of those he/she sees as competition. Then you'll get a lot of interesting answers.

Answer 2

I would define a manager as a person who exercises control and authority over the method of action employed by others to achieve a goal.
