A while back, I bought a book titled, For Writers Only (Ballentine Books). The author is Sophy Burham. I found it extremely interesting and enjoyable because it contained thoughts and experiences of famous writers about the writing process. This book does not offer writing tips. What it does offer are emotions that many writers experience while in the writing process. From nerves about getting started to finding joy in the art of writing. There are chapters on how these writers discipline themselves to write, how they know when to let go of the story, how they make time for their personal lives, the aloneness of writing, writer's block, rewriting, rejection and getting published. Also included is a chapter on how some writers dealt with depression, alcohol, jealousy, etc., and still produced great writing.
Most of us are not famous writers, but I think we can relate to many of the emotions these very famous writers experienced. Have a pleasant writing day. Be good to yourself.
