I find that due to having a remote job and living alone (albeit with my lovely dog) I'm less inclined to work on a side project where I'm again alone. I tend to gravitate more nowadays to spending time with people and being outdoors.
I used to be really active on side projects when I was a teacher. I'd have my social interaction filled to the brim so side projects were a way to have some alone time and recharge.
Sports is a great way to achieve that
