I was in your position in 2016. Took me until 2021 to make the switch. But all that time I grew to hate my job more and more. In the end I was ready for a psychward. I was intentionally screwing up things out of spite, breaking my worktools every other shift because I threw them across the street and stuff like that.

I went back to school in 2021, but still had to keep doing my old job for the money. It was much easier to do the job with the propect of a better future, I almost started enjoying the job again. But that didn't last long. Eventually dropped the old job conpletely in 2023 and very happy to do so.

Now I'm finishing up my graduation assignment and I expect to get my bachelor in januari-ish. I'm 35 and starting my career as a software developer. It's not an easy time to start, but I've been networking and gaining valuable experiences so that I actually feel cautiously hopefull to be entering the job market right now. Also because I've been doing a related job for the past 3 years that gained me a lot of valuable experience.

TLDR: it's never to late to learn a new skill, but it's better to do it sooner than later. You don't want to stay in a job you hate and suffer the mental consequences of that.

you don't. just start learning shit and you will see what sticks and develop new interests.

life doesn't require a per-conceived path. a lot of people just make shit up as they go. my entire career has been that way.
