General Eisenhower would demonstrate the art of leadership with a piece of string. He'd put it on a table and say: "PULL it and it will follow wherever you wish. PUSH it and it will go nowhere at all. It's just that way when it comes to leading people. They need to follow a person who is leading by example."
At another time he said, "You do not lead by hitting people over the head--that's assault, not leadership."- Michael P. Green, Illustrations for Biblical Preaching
