One of my favorite Leadership examples comes from my student days at Cadillac in Detroit. You would see this document posted on bulletin boards, in offices, etc. It's called the Penalty of Leadership, and comes from a Cadillac ad placed into the Saturday Evening Post in 1915. It's great insight for anyone trying to become a leader or a change agent.
“In every field of human endeavour, he that is first must perpetually live in the white light of publicity. Whether the leadership be vested in a man or in a manufactured product, emulation and envy are ever at work. In art, in literature, in music, in industry, the reward and the punishment are always the same.
