Winston Churchill, one of the greatest orators in modern history, often spoke about success in life and politics. He was frequently misquoted on the subject, too. But we do know that he said, “Success always demands a greater effort,” as he wrote it in December 1940 to Australian Prime Minister Robert Menzies, while discussing troop deployments around the world and his plan to “gather a very large army representing the whole empire.” Ultimately, few people were more inspiring or influential in World War II than Churchill, in what was one of the most important and necessary successes in human history: victory against Nazi Germany and the Axis forces.
