I've been down this path and if I can give you any wisdom of what I've learned, this would be it.
1. The first thing is, is that you sound like you're already responsible for yourself and that's a good thing. You've recognized that you have needs for your survival and you've addressed them. This means that you're not dependent on anyone else and that's a good thing. My philosophy has always been, even if we lived in caves, we'd still have to work to survive. To eat, to give ourselves shelter and protection. If instead, we felt like going down to the pond and skipping rocks all day, we'd starve to death pretty quickly.
I hung around the art and music crowd for years. The #1 thing that bothered me was how dependent on other people, everyone else seemed to be. Everyone needed a ride, a place to stay, a hand out and so on. These same people would also constantly brag about going to the latest trendy place to eat, about their 10$ fancy coffee, the cool limited addition action figures they just bought, the latest video game, the new boots, the new outfit for the club / concert.
Everyone falls on hard times, me included, but is giving up your self sufficiency worth it, so that you can simply say you have more time for fun? or distraction? isn't' that what it comes down to? a fear of missing out? Yes, by working, you're giving up your free time and you won't have as much to keep up with the latest and greatest.. whatever it is. But also consider my next following two points.
2. you're already working 40 hours a week. awesome! you're also in control over how you spend those 40 hours. As there and back again was saying, most jobs in the business and corporate sector are going to be for extroverts, but there are plenty of jobs that have a meaningful impact on society that also don't require a ton of education. Nursing, EMS, fireman, social work or even jobs like IT, accounting, television productions. It's completely possible to be happy with a fulfilling career that will also allow you to support yourself. Use your imagination and be creative in looking for possible careers.
3. Your in control of who you want to be, on your own time. From your post, you don't sound like you're married of have kids. If you work an 8 to 5, you should have plenty of time to watch movies, listen to music, read comics, work on art, play video games.
I'm 46, I'm the single parent of an 18 year old and I own my own home. In my car and at my desk (with headphones) I'm listening to everything from techno to heavy metal. At home, I'm working on DIY art / house projects, I write music, I take my son to comic con, we go camping, kayaking, on saturdays I work and play at an airsoft field (it's like paintball). Pre covid, I used to Dj and play live shows occasionally.
But 8am Monday? I'm at work, getting it done.
I'm just going to level with you. I've always been a punk kid and this whole idea that society sucks and everyone is just a programmed robot is bullcrap. When I turn on the tap, clean water comes out. When I flip the switch, the lights go on. When I go shopping, there's food on the shelves and what makes all of that possible? The fact that people had jobs to do and they showed up and did them. Furthermore, the fact that I live in a stable, safe culture is something I'm grateful for. I don't go to bed at night worrying if I'm even going to wake up in the morning and that's something I don't think I can be thankful enough for. No, culture and society isn't prefect. There isn't one on earth that is. But, if you feel you have that much of a difference with it, work for change. Run for office, be directly involved in causes you feel the most strongly about. That in itself could be a career path for you.
The problem most people have isn't that society sucks and losing themselves is some kind of twisted conformity. Trust me, being "different" is just it's own kind of conformity, but that's besides the point. The problem is, is growing enough to understand yourself and how you fit into society enough to make the most of yourself and your abilities. It's hard and frankly, the whole process sucks. It's easier to blame society and to just quit and drop out.
As I was saying in the beginning, you recognize the need to be responsible for yourself and for that, I give you respect. It's entirely 100% possible to be satisfied with a career and still be yourself. It just takes work, that's that difference. Anything else is just excuses.
And I'm not some saint here, I've been up and down, back and forth and I've made excuses, but I never gave up and ultimately, I got where I wanted to go. It wasn't easy, but I made it.
