It is worth mentioning, for future reference, that the creative power which bubbles so pleasantly in creating a new book quiets down after a time, and one goes on more steadily. Doubts creep in. Then one becomes resigned. Determination not to give in, and the sense of an impending shape keep one at it more than anything. I am a little anxious. How am I to bring off this conception? Directly one gets to work one is like a person walking, who has seen the country stretching out before. I want to write nothing in this book that I don't enjoy writing. Yet writing is always difficult.
