Now the secret of this is, as far as he knows, the complete conviction that he is going to sleep, a conviction not expressed at all, but an acquired instinct. Yet he does not--he says all this at the risk of being accused of egotism, but hoping it may be useful--bother about the matter at all. Once he used to bother about it: that was in the days when he slept rather badly; now he does not. Nor does he go to bed in the hopes of going to sleep; he does not go to bed till he feels, instinctively again, that it is time. Thirdly, if he has gone to bed early, and is not going to be called till after he has had his fill of sleep (this is rare, since he is a glutton at it), he instantly reads or gets up instead of trying to go to sleep again (which in itself would do no harm), or instead of wondering why he has awoke. This would do harm, for it partakes of the nature of “bothering about it.” He avoids sleep during the day, this also he thinks is crucial, and if he feels sleepy (sleepy, not to be compared with inclined to rest) he gets up and does something. To return for a moment to his bedroom. The windows are open, there is no carpet, he has blankets which vary according to the time of year, but whatever the time of year he has an extra thickness over his feet. In his rare moments of semi-consciousness he sometimes (this is towards morning, always when the world is coldest) draws the extra covering over him, and without really waking sleeps again. He also invariably goes to sleep on his right side and invariably wakes lying on his left.
