I love photography and for a while (approx 20 years ago) considered moving to it as a full-time job. But it quickly became obvious that the actual shutter-clicking would be a tiny part of running an overall photography business (and then smartphones and Alamy happened and the bottom dropped out of stock photography). So I'm glad I stuck with my mainstream job. It paid well enough to live and afford expensive lenses and the wildlife trips where I could put them through their paces. And from my current 60-year-old perspective, it also paid for retirement savings and pensions which I wouldn't have now if I'd tried to be a wedding photographer, say.
The other thing that is sometimes overlooked is the importance of health. If you drop out and then get very ill, and have a very seat-of-the-pants lifestyle, things can get dark and uncomfortable very quickly.
Not to say which is the right approach, just pointing out that it's worth considering how different future-yous will look back on your decision now. One who prioritises memories over possessions. One who isn't healthy and feels the cold. One who wants children. Etc
I've thought that some IT jobs might fit the bill, particularly if one only needs to work a small number of hours each day.
When I was a teenager, I worked at a gas station, which was mostly low-stress and even had a lot of down time that I could use for reading. But the pay was terrible and I had no benefits.
It probably depends on what you're used to and how you handle stress.
I'm a web developer and find it incredibly low-stress in comparison to my previous lives. No back-to-back double shifts, no risk of working a full day and not getting paid for it, no abusive management, no rampant substance abuse at work, no "if you have time to lean, you have time to clean", no pressure to come into work when you're sick, no getting written up or even fired for being <5minutes late to work, no punitive scheduling... I could go on.
I see people complaining about the software industry and I really don't get it. This shit is so comfortable, easy and straightforward in comparison to the kind of work most people have to do.
