I can relate. I awaken way too often at 5 am, not the 8:30 am alarm time. I had gotten into a reasonable structure with two days of pickleball, one morning with fiber group, and writing a story a week for Medium. I live alone and have no kids or grandkids, so I truly am a free agent!
Then I got injured and while my week seems quite open (well, except for PT) I feel way more at odds and ends. It's almost like too much free time.
I'm now retired a little over a year and still adjusting and modifying. Trying some volunteer things and discarding what doesn't float my boat. Apparently, my boat is quite heavy and needs a bigger flotation device!
You will figure it out!
