Perhaps it’s time to find better hobbies? It’s a chore and difficult because you don’t know what you like/don’t like before you try it for some time.
Independent of finding girls it’s also good for your own psyche to get away from the screen. And if it has to be gaming perhaps you can find people who are into board games?
Back in the 90ies my uncle always got a book for the car hee owned which would explain how to disassemble it.
But me and my dad never bothered with the book, just got to work on it and figured it out on the go. The biggest thing I replaced in my car was the whole Chassis.
But yeah in the new cars there is less mechanical stuff and more electronics so it’s getting difficult.
The only place I can think off was YouTube, or if you can find a book like my uncle always had: https://onlymanuals.com/volkswagen/passat/volkswagen_passat_b3_workshop_manual_passat_b3
