When I arrived at school age I learned pretty well and was still regarded by many as being precocious in this respect; but I acquired knowledge rather by absorption than by hard study. A soft brick placed in water will soak up a quart in a few days. A human brick will likewise absorb a bit of knowledge if he only remains where there is something to be absorbed. As I did not engage in the usual sports and rampages of boys I took to learning rather readily. At the same time I became introspective and self-centered. The brain cells of the most stupid person are constantly in action. Cerebration goes on whether we will it or not. If we do not direct our brain it will run riot and lead us into devious and dangerous paths. The more I thought of myself, the more important I became; not proud and supercilious, but simply important to my own little ego. I speculated in my childish way, on the function of each organ of my body and the relation it bore to the great scheme which we call existence. One day I got to wondering what would happen if my heart should take a notion to stop and rest for a few seconds. The thought of such a catastrophe made me so nervous that all my organs apparently got out of gear and I had a diminutive fit. From that day I began to have all sorts of nervous symptoms, most of which were, to say the least, vague and indefinite. Frequently I complained that I was afraid "something was going to happen." Since then, whenever I hear that phrase I invariably associate it with a person who has nothing to do and who is too lazy to do anything even if he had ever so many duties. At that time I did not know enough about disease symptoms to enable me to acquire a perfect ailment of any sort, but later, when I had formed a speaking acquaintance with diseases, I began to get them rapidly and in the most typical form. For the present I took life as easy as I could and had no boyish ambition to be a cowboy or a desperado. Such ambitions as I did foster were of the free-and-easy sort. My first inspiration worth speaking of was after my visit to the circus. Every male reader has been struck by it some time during his boyhood, and it is a healthy ambition of which we need not be ashamed. Yes, I was going to be an acrobat and wear pretty red tights with glittering spangles! It would be nice, too, I thought incidentally, to be near the little lady who wore the pink tights and did such awe-inspiring stunts on the flying-trapeze. The circus sawdust ring and the flapping folds of canvas may lure boys from books and study, but they give us our first ambition to be and to do something. Mine was of short duration, however. It came and went like the circus itself.
