Dunno. I just have little motivation to put hours and hours into a challenging project that I probably won't complete. When I was working, I never had any side projects.
It's not like I'm sitting around on my ass all day. I walk the dogs, bicycle, rock climb indoors, and travel. I'm starting Tai Chi and just bought an e-drum kit. After I retired I spent a year renovating one house and have spent a lot of time this winter on another. Also lived off-grid in a forest for three summers and am doing it again this year. Off-grid ain't easy. Can't just turn on the faucet and presto hot water.
