The freedom you have in a working environment truly makes a big difference, as well as the compassion levels of your coworkers, supervisors, and anyone else you may be dealing with in your sphere of employment.
In my experience, when I was able to work more, the jobs that were the most tolerable were those where you could pass the time with good people and the work itself wasn't too physically demanding. No job is worth killing yourself for.
Usually, these were NOT professional, higher paid, office style environments, as those sorts of companies often impose a laundry list of rules, regulations, and procedures upon you that turn your life into a massive headache. The best employers are the ones who allow you to be a real, authentic, and genuine human being rather than forcing you to dress up and put on a sterilised HR endorsed act for breads and circuses.
I used to know quite a few people who picked up a skill like jewelry making, sewing, knitting, photography, etc and took on commissions and freelance work to make a living. This lifestyle was very enjoyable for them, because they got to make their own schedule and had more free time to travel and hang out with other people, while still keeping busy. If you're going to be self-employed, it's important something that takes up enough of your time to keep your mind sane, but not too much to the point where you're stressed out. The devil makes work for idle hands, as they say.
Idleness will drive a person mad too, so if you go down the tradesperson or be your own boss route you want to find a profession that's going to sufficiently occupy your time and mind enough to grant you some fulfilment.
