When I worked an overnight shift and lived alone, I got into a pattern of 2 to 3 hours a go three times a day. These were after work, halfway or so through my personal time, and before work. I used these separate times in between sleeps for work, almost exclusively for chores, and a dedicated slot for hobbies. I started each one refreshed, which was great. It doesn’t necessarily work so well when aligning your life with a partner.
