In the last analysis the world cares very little what you or I know, but it does care a great deal about what you or I do. An educated man on the streets, with his hands in his pockets, is not worth one whit more than an ignorant man with his hands in his pockets. It is the application of our knowledge in such a way as to help the world onward materially, mentally and spiritually, that is in the long run recognized and applauded by mankind.
