My problem is fun and work are so blended… although I guess that’s not really a problem
Fun Things include
Reading - LOTS, I’m at over 80 books read so far this year and expect to hit something over 100 easily. I like Science Fiction, Thrillers, Mysteries and Cozy Mysteries as well as some business books, and of course lots of farming and sheep and genetics books.
@RosemaryOrchard mentioned Writing and I’m a long time participant in NaNoWriMo. Already planning my sprint for this year. I’m usually a NaNo rebel, not always a new novel, and in fact this year will be year 3 on the first of my NaNo projects that might actually be worth publishing. I have a lot more to add to it that I’ve made notes on over the past year and plan to write another 50k words of new material so I have plenty to edit down later.
I spin yarn for several hours each night when we watch movies or other shows. None on regular broadcast TV, all of our watching is now Amazon Prime or Netflix but I get a twofer by spinning while I watch. I make scrapbooks, have a photography show coming up in November of my photographs at the local Pub, knit, weave, do some quilting, sew historical garments and some useful ones, enjoy catching deer (not so much into the hunting, but I like to eat them ) shooting sports, cooking, genealogical research (on the back burner now but it resurfaces occasionally) scanning and researching old photographs (working on 2 huge projects, 1 for the historical society and 1 for me personally), doing genetic calculations and programming on LambTracker (this blends into work). Most of the sheep farm stuff is fun to me, one reason I’m still doing it but technically that is also work. Secretary/Registrar/Treasurer for the American Black Welsh Mountain Sheep Association which registers all BWMS in North America, approved inspector of these sheep for the UK Association, also handle the white and chocolate Welsh mountain registries, active in local issues right now focused on stopping fracking of our watershed, Ditch company BOD member and that’s just the major things. I’m also trying to learn how to draw with colored pencils and do some limited painting. I’d like to travel more (not yet possible with no one to care for the farm) but we are working on that.
I’d start by listing any and everything you think you might be interested in or have ever been interested in and then make a point to dip a toe into the waters of all of them. You’ll find something you love to do I am sure.
