I'd been solidly in tech for the past ~9 years - DevOps software, eCommerce company, sales enablement software, etc.
I also re-picked up my hobby/passion of coin & currency collecting a few years ago and started buying and selling for fun.
The stars aligned in such a way that fairly recently I've been able to focus purely on the numismatic world, and I'm now doing that full time (and then some).
My life now consists of about 50% time on the road at physical, in-person coin & currency shows all over the country. I stand at my booth and buy & sell, run around the floor making deals, hunt other dealers cases for treasure in plain sight, and all that fun. So I wouldn't exactly call this "manual", but show days are very much in-person and 12+ hours of being on your feet brain fully-engaged.
(I spend the other 50% of my time at home working on the software that powers my operation, buying & selling on eBay, going to and from the post office, etc.)
But man, this is SO MUCH FUN. I describe my former life as "arguing with people on Zoom all day" and my current life as absolute heaven indulging in a super fun hobby that actually makes money. There's also an incredibly cool social aspect to it wherein you kind of see the same dealers at all the big shows, so it's a bit of a traveling circus ("see you next week in Phoenix?")
