A short blurb from The 7 Habits of Highly Effective People calendar explains one difference between leaders and managers:
“Effective management is putting first things first. While leadership decides what “first things” are, it is management that puts them first—day-by-day, moment-by-moment. Management is discipline and the act of carrying it out. The word “discipline” derives from “disciple,” which means one is a disciple to philosophy, principles, values, an overriding purpose, a subordinate goal, or a person who represents that goal.”
Which would you rather be: A leader or a manager…why not strive to be both?
