“ Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful [people] with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan "press on" has solved and always will solve the problems of the human race.”
         -- Calvin Coolidge (30th President of the United States)
