Look, a job is a job and work is well, work. As noted in the other comments trades are hard work. Far harder than a desk job. I would suggest not romanticizing the trades as some replacement for a desk job. Go do some trade work in your free time (go build a fence in the middle of the summer as an example) and really find out how much hard work it is. If you still enjoy it after being in 95 degree heat for 8+ hours while hauling thousands of pounds of concrete, then a job change might be right for you. But first try it as a hobby.

I say this with lots of experience. I do a lot of trades work as a hobby, but the reality is in most cases it is labor of love. I'd be more efficient with my time and money by hiring it out.

I second this. I've performed many jobs around my house, and while I don't regret any of them, there are many I would never do again.

This kind of work has turned out, in almost all cases, to be far more difficult and time consuming than I expected.
