A long time ago. Now I just do it on the side but knowing how to fix cars has always been a good “in” to get girls to talk to me but from there I still had to actually get them to go out with me and see where it went. It’s not like I was just straight up trading car repairs for sex.
I use WSL for cli stuff and I have Mint running in a VM for desktop stuff. I briefly tried dual booting but it was a pain in the ass and I ended up rarely switching to the Linux partition in practice.
