"To survey with wonder the changes of one's own self is a fascinating pursuit for idle hours. The field is so wide, the surprises so varied, the subject so full of unprofitable but curious hints as to the work of unseen forces, that one does not weary easily of it. I am not speaking here of megalomaniacs who rest uneasy under the crown of their unbounded conceit — who really never rest in this world, and when out of it go on fretting and fuming on the straitened circumstances of their last habitation, where all men must lie in obscure equality. Neither am I thinking of those ambitious minds who, always looking forward to some aim of aggrandisement, can spare no time for a detached, impersonal glance upon themselves."
