I wrote 13 pages again today. Thought it was 14, but then I did the math in my head again. I have a wall calendar on which I write down my day's pages, keeping a running total for the current book and also for the month. I've been doing that for at least 40 years. After our house burned down in 2008, I tried to stop keeping track of my pages that closely and also tried to stop keeping a list of every book that I read. I found that I just missed that structure and routine too much and went back to it very quickly.
