I want to learn Vim and tried several times (with vim modes form Intellij mainly) but failed under pressure to get actual things done. I see great potential and I know I have to sacrifice 1-2 month of productivity to get up to speed but I fail every time.
Once I learned the basics, I only use vim itself for commits and small scripts, but this made using vim /modes/ in spacemacs and VSCode practical.
Without the basic vocabulary it just feels like turning on 'cripple mode' while you're trying to get work done.
I'm still not an expert; I heavily reuse the same ~15 commands. I've found learning that vocabulary to be very much worthwhile.
