I did an enlistment in the Navy as an engineer. Blue collar work everyday. I enjoyed it. Worked a series of blue collar jobs to put myself through the engineering program at State U. Delayed graduation that way (never delay graduation, you're just delaying being better paid). I really enjoyed being active.
Today I have a good mix of topics that I do for my job. I'm in a jack-of-all-trades situation and can't complain one bit. I'm the "expert" for my department on several topics. That still makes me laugh at myself.
If you want to pursue the trades may I suggest you start out studying what you want to learn via library, YouTube, and used books and give it a test drive.
I have a home workshop in the garage. I've built all sorts of things over the years - cars, motorcycles, scooters, furniture, refinished furniture, etc.
If you like doing something like that - practice those skills for yourself in your home workshop, frequent the various forums like Practical Machinist, Garage Journal, Welding Tips and Tricks, etc that apply to your current fascination and feed your brain information. Outfitting a home workshop can be a slow process where you buy used quality tools which done right can still be sold for similar prices later. Or you can go crazy and spend $25K overnight which I don't recommend. I have a mix of good and cheap tools that I have acquired over several decades as the need came up.
Fix up your house, landscape your yard, build an old car, sell, repeat. Allows you to do the work you love without dealing so much with picky customers. This item was your's, you built it your way or you fixed it to your taste. Then you sold it. The buyer can take it or leave it.
It should also let you set the pace of this side-gig rather than working at the pace of your's customer's expectations. If you love what you do and it generates cash enough then you could translate this side-gig into something more full-time.
