Nothing in the world can take the place of persistence.

Talent will not; nothign os more common than unsuccessful men with talent.

Genius will not; unrewarded genuis 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
