Title: Late 20s, didn’t finish high school, and I have no idea what career would fit me. What would you suggest?

I’m in my late 20s and live in Japan. I didn’t finish high school.
I’m currently trying to figure out what kind of job I should do next, but the problem is that I don’t really have a specific career I want to pursue.
So instead of asking “How do I get into X career?”, I thought I’d describe what I’m like and see what complete strangers would suggest.
A few things about me:
I get bored very easily.
When something interests me, I’ll usually just try it.
But I can also lose interest pretty quickly.
I hate doing the exact same thing over and over.
I don’t like being micromanaged.
Social dynamics at work can drain me pretty quickly.
I’m generally comfortable working alone.
I tend to notice and analyze people’s behavior, tone, and little details.
I’m better at figuring things out as I go than making a 5-year plan and sticking to it.
I enjoy researching things I’ve never heard of before.
I like coming up with ideas, but I sometimes lose interest during the process of actually finishing them.
Money obviously matters, but I don’t think I’d last very long in a job with zero freedom or autonomy.
Given all that, what kind of work do you think might suit someone like me?
I’m especially interested in careers or jobs that someone in my situation could realistically get into in Japan without a high school diploma.
It doesn’t have to be a conventional career either.
Honestly, I’d love to hear about jobs I’ve never even considered before.
Throw anything at me.
