The Origins of Servant Leadership?

From an Inc. Magazine post:

“The Greenleaf Center, which Keith presides over, takes its name from Robert Greenleaf, the originator of the concept of servant leadership. …”

I think that would come as a surprise to Jesus who said, “If anyone wants to be first, he shall be last of all and servant of all.” (Mark 9:35 NASB).

Does this make the second “Under the Sun” sighting in a week?

It makes me wonder, how often do I live as a copy but think of myself as an original?
