“It may be necessary to repeat the process a few times, but in the end, if you have shirked nothing in facing the worst possible issue, you will find that your worry disappears altogether, and is replaced by a kind of exhilaration.
This is part of a more general technique for the avoidance of fear. Worry is a form of fear, and all forms of fear produce fatigue.
A man who has learnt not to feel fear will find the fatigue of daily life enormously diminished. Now fear, in its most harmful form, arises where there is some danger which we are unwilling to face. At odd moments horrible thoughts dart into our minds; what they are depends upon the person, but almost everybody had some kind of lurking fear.”
