President Ike Eisenhower once demonstrated the difference between leadership and management to his cabinet by putting a piece of string in a straight line on the conference table. He then asked one of the attendees to put his finger on one end of the string and push it. The string, of course, bunched up in an ugly bundle. He then asked the man to pull the string with his finger on one end. The string straightened up in a nice neat line and followed the finger across the table.
