Listened to an interview of John Grisham on the Longform podcast. He spoke about writing one page per day.
To work on it at the same time and place. It sounds like he has done his early in the morning. I know that Hemingway also had often done his writing early in the morning.
I have been waking up earlier, I just need to get up and focus on writing, putting words on the page, as it were.
