Education will not; the world is full of educated derelicts. Persistence and Determination alone are omnipotent. The slogan Press On, has solved and will always solve the problems of the human race.”
—Calvin Coolidge (18721933)
“An interesting play cannot in the nature of things mean anything but a play in which problems of conduct and character of personal importance to the audience are raised and suggestively discussed.”
