I will mention here another habit which had grown upon me from still earlier years,--which I myself often regarded with dismay when I thought of the hours devoted to it, but which, I suppose, must have tended to make me what I have been. As a boy, even as a child, I was thrown much upon myself. I have explained, when speaking of my school-days, how it came to pass that other boys would not play with me. I was therefore alone, and had to form my plays within myself. Play of some kind was necessary to me then, as it has always been. Study was not my bent, and I could not please myself by being all idle. Thus it came to pass that I was always going about with some castle in the air firmly built within my mind. Nor were these efforts in architecture spasmodic, or subject to constant change from day to day. For weeks, for months, if I remember rightly, from year to year, I would carry on the same tale, binding myself down to certain laws, to certain proportions, and proprieties, and unities. Nothing impossible was ever introduced,--nor even anything which, from outward circumstances, would seem to be violently improbable. I myself was of course my own hero. Such is a necessity of castle-building. But I never became a king, or a duke,--much less when my height and personal appearance were fixed could I be an Antinous, or six feet high. I never was a learned man, nor even a philosopher. But I was a very clever person, and beautiful young women used to be fond of me. And I strove to be kind of heart, and open of hand, and noble in thought, despising mean things; and altogether I was a very much better fellow than I have ever succeeded in being since. This had been the occupation of my life for six or seven years before I went to the Post Office, and was by no means abandoned when I commenced my work. There can, I imagine, hardly be a more dangerous mental practice; but I have often doubted whether, had it not been my practice, I should ever have written a novel. I learned in this way to maintain an interest in a fictitious story, to dwell on a work created by my own imagination, and to live in a world altogether outside the world of my own material life. In after years I have done the same,--with this difference, that I have discarded the hero of my early dreams, and have been able to lay my own identity aside.
