Robert Henri, The Art Spirit: Notes, Articles, Fragments of Letters and Talks to Students, Bearing on the Concept and Technique of Picture Making, the Study of Art

Be game–take a chance–don’t hide behind veils and veils of discretion… Go forward with what you have to say, expressing things as you see them. You are new evidence, fresh and young. Your work, the spirit of youth, you are the progress of human evolution. If age dulls you it will be time enough then to be ponderous and heavy–or quit. It takes a tremendous amount of courage to be young, to continue growing–not to settle and accept.
