Leaders desirable to be confident of "quartet" IN ALL, and engage in recruiting teams of people who are in some ways, maybe, and three, but in some cases - FIVE.
Leadership is needed to turn a group of people into a TEAM.
Leading is the same thing, this is a doubling of effort and talent in conditions where goals can already be forgotten (= Ego's work in Ego name).
