When I was 19 I got my electronic technician highschool and certificates done. Didnt find a single job for a whole year but I didnt look into anything outside of electric work.
Then I got into fast food and supermarket work for a year. Told straight up I have no experience but I would love to learn to do anything and have a job. Got the tiniest money out of that, but quickly realized people work this shit till they are 30 or 50 or pension and they are forever poor, miserable and dumb, its a dead end slavery tier boring retarded job.
At 21 I started noticing welding shop 20 minutes from my home. You can learn to weld like a professional with a few youtube vids that all last 5 minutes or so, welding is extremely simple thing to do. So I phone the place, said I saw a hiring ad somewhere and decided to phone (there was no ad), said I had some experience (I didnt, I watched yt vids) and that I would be perfectly happy to work full time as a helper for half the pay.
Three months later, I saw all sorts of welds imaginable and I could use all welding equipment like an actual professional. So I bought the cheapest welding equipment I could from my 3 monthly paychecks I received so far, and started selling the services on my own.
Today, Im a proud fence builder, boat repairer, metal constructions guy (dont know all the English names), roof layer (some roofs are built by screwing panels on top of a metal construction on the roof that is hammered in the walls), truck fixer, custom repairs guy, window bars installer, metal door installer, cage maker, custom metal box maker…….
So I mean I'd hire the this guy, put a torch in his hand let him slowly drip a metal stick on a line where two metal pieces touch. Im 25 and I own most of my business, still paying for the huge empty warehouse I turned into a workshop. I have 2 highschool friends working with me and we all make slightly more than the national average. We pick the jobs we like and avoid ones that seem too demanding or pay bad.
You know sometimes people will tell you to go fuck yourselves. Sometimes people will have an understanding and give you an opportunity even if you dont have any certifications or anything, but are willing to try or learn.
I suspect plumbing and.. repair services (dont know English for people who repair air conditioning, boilers, washing machines) could be learned from youtube, applied to at a legit job, earning enough in less than 6 months to buy all the necessary gear, and started out. Lots of these skills that arent really all that difficult to obtain and yet pay much more than the minimum wage, and you get to blast music, pick hours, work with people you like, comb through the jobs…
I mean I dont know what else to tell you. Other than best of luck. If you have 0 work experiences AND are disabled, then I think you are kinda fucked. No clue what to tell people in those conditions. This guy could be slightly mentally impaired, but I dont think he wouldnt become a good welder in… 2 or 3 months.
