I had a don't pay others for what you can do yourself mentality instilled from a young age, but really learned after getting my first car. It cost $500 and was 35 years old. If I wanted freedom I had to keep it running. I quickly learned I couldn't afford to pay a shop to fix every minor thing and the quality of work was less than stellar, also that there was nothing I couldn't take apart, try to fix, and put back together no worse than I started if I couldn't figure it out. After a few years I could rebuild engines, transmissions, do body work, and everything to maintain an old car. These mechanical skills easily transferred to maintaining a home, building walls, hanging and finishing drywall, load calcs for floors, beams, plumbing, electrical, etc. and everything else relevant to building and maintaining a house. Admittedly I could use to be a lot better with sewing, upholstery, and repairing clothes but I think that's in part a different skillset. I learned before youtube was a thing but while the internet was a good resource but not as easy as it is now. I think they key is to start with something, anything (car, bike, room, garage, etc.), and be able to work and expand your limits with minimal consequence.
