I got relatively good at vim N times counting some years back (but forgotten it now as I don't use vim as much these days). It was a practice thing. I made a point to never repeat a command more than twice and after a while it became second nature. I even got really good at guessing how many lines away things were (but nowadays I just use relative line numbers).

I never became fully fluent, but I also didn't try too hard over the "don't repeat commands" thing. And I got lazy after about a year (but also used other editors a lot more, due to team members using them and such) and over time lost the ability. Some day perhaps I'll make a point to learn again, but for now I mostly use VSCode without vim mode...
