Nothing in this world can take the place of persistence.

Talent will not; nothing is more common than unsuccessful people 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 US president, 1872-1933)
