When I was young I longed to write a great novel that should win me fame. Now that I am getting old my first book is written to amuse children. For aside from my evident inability to do anything "great," I have learned to regard fame as a will-o-the-wisp which, when caught, is not worth the possession; but to please a child is a sweet and lovely thing that warms one's heart and brings its own reward.
