Paddling, Working Out, Running/walking/bike (leisurely walk on non-running days), practicing/guitar lessons (been slacking on that), enjoying coffee/tea each morning rather than rush the caffeine shot, planning/taking day-trips and longer trips, Euchre club, reading, catching live music a few times a week. I'm also starting to give bike history tours for a friend's business but so far that is ramping up slowly. Sweet spot for me would average twice a week (takes up about 9:30-2:00 of my day but a lot of fun and I'm happy getting paid to do something I'd almost do for free. They are scheduled 3 days a week but not all days are booked and I can refuse tours if I have other plans. The tours fit well as late morning and early afternoon are usually unstructured free time for me after my morning routine of coffee/working out and before afternoon activities start.
Started dating another retiree so that's taking up even more time and messed up my routine a bit as we spend more time together. I'm feeling guilty not practicing guitar as much as I'd like and I've had to renew my last library book 2x as I've been so busy.
