My suggestions:
-
start with whatever distro you think looks cool. It doesn't matter. Obv don't start with one that has a reputation for being challenging, like Arch or Gentoo. Personally I started on Ubuntu, but that was 15 years ago. If I were to start today, I'd probably start on Mint? Maybe Endeavouros? Idk. Check distrowatch if you want to know what's out there.
-
No matter what you choose, you, like everyone else, will end up trying all the big ones at some point. It's fun. You're not getting married, it's just a place to start.
-
take it slow. You don't need to switch all at once, and it's probably bad if you do. Linux takes work sometimes, and there's not always warning when trusts going to happen. So have a fallback, something stable you can use when you just don't have time to fix things. I still use Windows for video games (mainly because Bill Gates is a piece of shit who did and still does everything he can to destroy knowledge sharing and open source).
-
To exit Vim, hit escape a few times and then type :q enter.
- alternatively, don't exit Vim. You shouldn't need to. It's all you need, not just in computing, but in life.
