Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I do plan to sub, and I'm trying to get some tutoring gigs going because I really loved the teaching part, but as anyone in education knows, the ancillary duties create too much frustration, hence my retirement both times. This last time, thanks to the pandemic--my double dipping job required that I teach kids in front of me, kids on a Zoom call, and kids in another location all at once. It was wretched.
If you plan to substitute teach, why did you retire at all? You know the schools are dying for subs, and they'll be getting a great deal by paying you a pittance per diem pay. It's time for you to go into a completely new chapter in your life.
It pays to have hobbies and interests that can give you something to look forward to. For example, I'm into building and I seldom stop working on something. We travel once or twice a year overseas (in most years.) And I have a lake house with two boats. My wife and I are very busy with our church too.
