Nothing in the world can take the place of 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
