"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 determinations alone are omnipotent.
The slogan "press on" has solved and always will solve
the problems of the human race."
(Calvin Coolidge)
Presidente Estados Unidos 1924-1929
