For we should study pictures not solely for their own sake, but also as a means of making our lives fuller and better. If you ask me what is the most beautiful thing in the world, I shall not say art, although I am writing about pictures--but life--its fullness of possibility and abundance of opportunity. Especially young life; the lives of you girls and boys, who, as yet, have so few mistakes to regret, so much to look forward to of promise and fulfillment. What you will make of those lives of yours may depend a little upon schools and teachers, parents and friends, money and health, and many other things, but most of all upon your own wills. I wonder if you have read the life of Robert Louis Stevenson?
