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 alone are omnipotent.
The slogan 'Press On' has solved and always will solve the problems of the human race.
— Calvin Coolidge 30th president of US (1872 - 1933)
