Welcome to the club! I can’t I’m an exclusive vim user since for work I just need to get stuff done and jetbrains is fantastic for that…
But, as ~yretek said, just learn what you need and go from there. I’d sometime google “how to do x in vim” and be blown away by how crazy powerful vim can be! Something like registers or macros or inserting text from the output of a command!
So, I guess, enjoy the ride and take a look at the manual to get an idea of what it can do and dig deeper only when you need it.
