I knit. When I'm not busy knitting gifts for my family (instead of buying), I knit hats for chemo patients. There's a wonderful community of knitters in most towns and cities, and online too (ravelry.com!). Great way to spend time, keep busy and help people. And you're typically learning new skills regularly. I also am learning to spin, sew, and weave. The sewing helps me mend things instead of buying new, reuse things instead of tossing them. Spinning and weaving are just fun, although I'm hoping to be able to make my own yarn blends. If it works well, there are places to sell it online.
I also work out. And read. And garden. And care for my chickens. And cook. And can. So - yeah. There's a lot of things to do.
