If there was a man that lived who defined the true essence of raw competitiveness, then he was Ioseb Besarionis dze Jugashvili, better known as Joseph Stalin.
He became leader of the USSR from the early 1920s until his death in 1953. It is said that he prohibited his guards from entering his private bed chambers even on pain of death. One day, in a test of their resilience, Stalin decided to scream as if in great agony. When his loyal guards came to their master’s aid, they were duly executed for failing to follow orders.
