This is the way of many writers. Their muses and their moods react upon each other in a kind of unending circle. When they are unhappy they cannot write; but when they are busy with writing, and they know that it is good, they grow happier and happier. Then when they have finished and the first intoxication of achievement has worked itself out, depression comes again. And then, while they are yet too exhausted for a new effort, all their work seems futile and worthless, and all life a meaningless blank. And until the next creative impulse restores their confidence and vigour they are, comparatively, miserable.
