"Nothing in the 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 alone 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."
