“So the point of my keeping a notebook has never been, nor is it now, to have an accurate factual record of what I have been doing or thinking. That would be a different impulse entirely, an instinct for reality which I sometimes envy but do not possess. At no point have I ever been able successfully to keep a diary; my approach to daily life ranges from the grossly negligent to the merely absent, and on those few occasions when I have tried dutifully to record a day’s events, boredom has so overcome me that the results are mysterious at best.”
