We all have times during the day when we do our best work. I do my best writing in the morning, the closer to the time I wake up the better. That's when I'm most in touch with my subconscious and my muse. Ideas come easily and the writing flows. Pages add up with no great effort. If I get a good start and then have to take a break I can go back later and continue writing with no problem.
However, if I don't start writing until later in the day, after assorted distractions have had time to lodge in my mind, then things get a lot harder. Writing becomes work. Sentences are toil, paragraphs hard labor. Two or three pages wear me out. That's why I don't understand writers, or anyone else, who don't hit their stride until late at night.
Today, my work time was very disjointed, had to go back to it four separate times, but I got my early start and each time I returned to the keyboard I was able to pick up where I'd left off with no problem.
Today's writing dealt with the protagonist trying to resolve one of the novel's main subplots. A word about that: A subplot shouldn't exist simply to provide the reader with something else to carry him through the story. It should be integral to the story and by the conclusion should dovetail into the main storyline, making the ending all the more satisfying.
I wrote six-plus pages today.
Day 47 of writing my new novel is done.
