Well, it took me three years to decide to go back to work after 29 years of police work, then another two years to find something agreeable. The first year was like being on vacation (we moved to a different state/less congested area) and yeah, I spent a LOT of time on the screened-in back porch enjoying not having to do anything. SIL, a wise nurse, surmised that I was "decompressing". In hindsight, I'd say she was right. The first winter we had a 2.5 foot snowfall and I didn't go any farther than the mailbox for a week, and loved it. Like you, I hate cold weather.
"The Plan" at retirement was that DW and I would both get part time jobs, but around here none of them pay enough to cover commute expenses so there's no point to that. She's gone back to school 15 minutes away to finish a BS degree she stopped working on because of some family issues that demanded her time. She's going slow, just one class per semester, and enjoys having free time to spend with family nearby. I think she adjusted better than me, we both left high-pressure jobs. When the degree is finished in two years she wants to look for a low-impact part time job.
The college catalog just doesn't have anything that interests me much. Don't know why, a lot of people enjoy that. Just not my style I guess.
Then I started to get looking for something to do. For about 20 years I was enthused about radio control airplanes, but the interest waned the last couple of years of years before retirement - I guess I just plateaued with that. The intention was to resume at retirement but the interest just isn't there so I'm selling that stuff off.
Bought a small boat & outboard to try fishing and exploring the river. That's fun but not every day and no way I'm doing that in the winter.
For about a year and a half I was helping a friend build an airplane - Pitts Special - and did a couple of short-term contract jobs in computer forensics. That's out now, my certifications expired and one really has to be full time in that field to stay current. It changes fast.
So I just started the training phase of a job last week, the specific goal in mind being either a travel trailer or another full-size airplane. I had an airplane in my mid-20's. But since I've "been there done that" I suspect the travel trailer will win. So for now I'm working with that goal in mind. The job also has a much lower stress level so I think it'll be easier to go to.
But it sure is nice knowing that I don't HAVE to work if I don't want to!
I heard the call to do nothing. So I answered it.
