Milton Friedman

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 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

The most happy marriage I can picture or imagine to myself would be the union of a deaf man to a blind woman

— Samuel Taylor Coleridge, poet, critic, and philosopher (1772-1834)
