"Nothing in the world can take the place of perseverance. Talent will not; nothing in this world is more common than men [or women] with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Perseverance and determination alone are omnipotent. The slogan 'Press on' has solved and always will solve the problems of the human race."
Calvin Coolidge
