Similar for me. Nothing will teach you more about cars than driving a piece of crap. Something broke off my old Accord every time the wind blew. Also, the other way to learn is by reading... everything from magazines to forums.
<< LOL, Psycho 😉
Alot of my learning came from me being too poor to pay a mechanics bill in my teenage years 😉 one of my 1st trucks I owned had the fuel pump and the master cylinder go bad, I priced them out and the places I called wanted a lot of money to repair... so instead I ended up at Checker Auto-parts and picked up the parts, (both were $11.99 with a lifetime warranty on em) and a Chiltons manual, they are not the best books but hey for a poor kid they worked great. Anyway the Fuel pump ended up being only 2 bolts and 2 fuel line's and on putting in the new one holding the push-rod up. The master cylinder was again 2 bolts and 2 brake lines. Then the need to have a friend pump while I figured out how to bleed brakes right 😉
Basically odd and end things like this happened (had to change the wheel lugs when I busted em off 4x4'n real hard 😉) but that truck was very simple to work on, (GM 350) the most simple, straighforward, and inexpensive engine I ever had. From there I just seem to have a basic understanding from what I had experienced. I've looked over that howthingswork.com and it has some really great articles, also hanging out on the forums, since the Camaro/Corvette share the same motor as me just in a different config, I hang at LS1.com for anything I need help on there. Most of it has been for Modifications, right now I'm looking into a water-injection and a few guys have done that with the same Supercharger I put on mine.
But really, if you can get an old vehicle to work on, or help a friend work on his, you'll get a feel for car mechanic's I'd say, just get yourself comfortable doing things yourself, start out with easy things, or like me stuff you needed too 😉.
I get new things that come along all the time, a few month's ago my GF's car is a Acura Integra with about 140K miles on it now, but one day her clutch would just sink to the floor, after lookin around on some sights I learned about a "Clutch Master-Cylinder" I never knew about it before as I've always had vehicles with linkage to the clutch instead. Anyway it was just low on fluid was all. So the benefit of the internet is great to have. Keep lookin, reading and askin on forums, each car type has some good forums for it. If you don't have a fear of getting into it and taking your time to do it right you'll do great 🙂 >>
