Maxwell Perkins Quote
Writing a novel is a very hard thing to do because it covers so long a space of time, and if you get discouraged it is not a bad sign, but a good one. If you think you are not doing it well, you are thinking the way real novelists do. I never knew one who did not feel greatly discouraged at times, and some get desperate, and I have always found that to be a good symptom.
