The first night.
This idea of flipping schedules on purpose is fascinating, Adam. Thanks for sharing how you are doing it. How do you find your mornings? When do you wake up? I was a natural Night Owl as a kid, which only got more so in college. Then my first job was on the night copy/design desk at a newspaper, which meant I worked 4 p.m. to midnight. And though there are definitely downsides to that schedule, as a single 20-something, it was also great. My brain was totally in its groove 11 p.m. to midnight, right on deadline. I went to bed at 2 or 3 a.m., and I never had to have an alarm. I always got my 8-9 hours of sleep. I could go to the beach during the day. But then, after I got married and had a baby and switched to a 9-5 job, it was very hard for many years. I finally got a sun lamp and trained myself to the new morning rhythm. My creative brain can work early now, though it never feels as good as it used to at night — wee hour creation was almost euphoric. The ideas would come and come at night, and the writing window felt so delicious. You have made me think about the possibility, a decade or two from now, of flipping back to Night Owl one day. Very enticing. I am enjoying hearing about this journey. Good luck! I'm glad it's going so well so far.
Interstitial journaling is intriguing. Sometimes when I’m free writing my morning pages (yup, not a night owl), I sort of do this, but in a run-on paragraph, never with time notations. Hmmmm.
