Blake

“As the uneasiness and reluctance to face it cut him off more and more from all real happiness, and as habit renders the pleasures the vanity and excitement and flippancy at once less pleasant and harder to forgo...you will find that anything or nothing is sufficient to attract his wandering attention. You no longer need a good book, which he really likes, to keep him from his prayers or his work or his sleep; a column of advertisements in yesterday's paper will do. You can make him waste his time not only in conversation he enjoys with people whom he likes, but also in conversations with those he cares nothing about, on subjects that bore him. You can make him do nothing at all for long periods. You can keep him up late at night, not roistering, but staring at a dead fire in a cold room. All the healthy and outgoing activities which we want him to avoid can be inhibited and nothing given in return, so that at last he may say...'I now see that I spent most my life doing in doing neither what I ought nor what I liked.”
― C.S. Lewis, The Screwtape Letters
