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
