Nothing in this 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
