Nothing in the World can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent. The slogan press on has solved and always will solve the problems of the human race.
John Calvin Coolidge, Jr. (July 4, 1872 January 5, 1933) was the twenty-ninth Vice President (1921-1923) and the thirtieth President of the United States (1923-1929), succeeding to that office upon the death of Warren G. Harding.
