I have never had a W-2 job. Started in 1983 doing computer stuff while in college. Mostly retired in 2015. Finally cut my last client off in 2020. Which happened to be my first client 37 years prior.
Most all of that time, I worked from home. I heard more than once "Cool, you're always at home." My answer was always "No, I'm always at work." You can't get away from it. Sit at the desk for five minutes to do something "quick", and several hours later you are still there working on stuff that has to get done. It wasn't so bad the first 15 years or so. People were still so used to doing everything on paper, they could (mostly) easily go back to paper, until an issue was resolved. So, I was able to take a lot of time off. A lot of 1-3 week trips, mostly camping and hiking. A few trips got cut short, but that was rare. Then, the last 15 years I worked, everybody became so dependent on (or addicted to) their computers that they couldn't stand to be down an hour. Much more demanding, and even weekend trips became difficult.
Anyway, the whole point of this is don't pick something that you can't get away from. I surely would not go into computer/network/tech stuff, or a similar type work, again. Think of a service type industry where you can schedule out (and around your time off), and are able to say "no" as needed. Something that "emergencies" don't come up. Not seasonal. Low overhead (no office, shop space, etc). Off the top of my head, I would think along the lines of things like pressure washing, carpet cleaning, fleet wash, etc.
And don't get me started on employees (or 'partners'). I swore off ever having another employee.
