“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 more problem of the human race.”
-Calvin Coolidge, 1923. "Silent Cal" did not speak often, but when he did, people listened.
