This is not by Churchill, but Churchill quoting his colleague Arthur J. Balfour (Prime Minister, July 1902 to December 1905) in his book Great Contemporaries (London & New York, 1937, last reprinted 1990). The citation is on page 250 of the first edition, in the chapter entitled “Arthur James Balfour”: “…’there were some things that were true, and some things that were trite; but what was true was trite, and what was not trite was not true’…” Living and life You make a living by what you get; you make a life by what you give. Reiterated in many sources including a 2005 TV ad by Lockheed Martin. An old saw put in Churchill’s mouth.
Churchill had shown signs of fragile health as early as 1941, while visiting the White House. At that time, he suffered a mild heart attack and, in 1943, he had a similar attack while battling a bout of pneumonia. In June 1953, at age 78, he suffered from a series of strokes at his office. The news was kept from the public and Parliament, with the official announcement stating that he had suffered from exhaustion. He recuperated at home, and returned to his work as prime minister in October. However, it was apparent even to him that he was physically and mentally slowing down. Churchill retired as prime minister in 1955. He remained a member of Parliament until the general election of 1964, when he did not seek re-election.
