Persistence

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, potus 1924-1929
