Craft.
I have begun to craft again. Cross stitching, diamond painting, etc. I want to try new crafts to stretch myself like painting (paint my number kits...I am comfortable following directions rather than open ended), I want to try knitting or crochet, puzzles are fun, I glue them up and mount them and have a whole wall of them.
lots of YouTube on anything you can thing of to get started on any hobby.
It’s getting colder so keep in mind to find indoor activities as well as outdoor.
