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. <br /><br />-- Calvin Coolidge, Thirtieth US President 1923-1929
