That's what I came here to say. Find a math/ science adjacent hobby (note: hobby must be expensive) to devote a disgusting amount of time researching, then use some of those skills to find a job. I like computers, 3d printers, and cars; I got a job servicing and installing industrial equipment.

Sometimes you don't even have to partake in the expensive hobby. Just spend weeks reading about it on Wikipedia and forums and watch a few dozen hours of YouTube videos on it and you're bound to get enough side knowledge to be useful in some field.

This was also me with music production. Then I got a MS in electrical engineering and I can't stop talking about math.

I'm thankful that I've been able to resist, so far.

I want to get into it, especially since I now have a 3D printer and can print custom parts, but even that hobby itself is getting to be expensive.

signal generator - $2000

oscilioscope - $200000

nope, and that confirms it.

Tbf I heard universities don't require rich parents in sane countries.
