small town life
I think a lot of us dream about earning money by doing what we love. Semi-retirement is the perfect time to do this, since have more time and freedom, and any income earned is (very hopefully) supplementary.
Small-town living is a nice compromise between farm and "big" city life, and has a lot of perks. You have a better view of the Milky Way, less traffic, and lower crime rates than in the city, but you also have a community of people watching out for you and lending a hand when you need one.
Here, I can still buy a house at an affordable price and my groceries don't require a second mortgage. I'm not sure if there is more to do here or if you just get to hear everything that's going on but there's nothing sleepy about small towns. And sure it takes you 45 minutes to buy a loaf of bread because you have to chat to everyone, and you get embroiled in the minutiae of the lives of others no matter how much you resist the dark side of alluring gossip, but at least you're getting in the game.
