the best part about learning vim, at least the basic movement and operations, is that pretty much every good application that involves text has a vim mode/plugin which means what you learn can also be used outside of CLI.

learning it takes time, i started with basic movement and then each week incorporated a new command into my workflow. it really does make text manipulation faster, but also if you don't modify text frequently then yeah nano is fine or in a GUI Kate is also great (has a good vim mode and you get a gui so you won't get stuck).

It was a bit to get used to for me as well, I switched fully to Linux around 2020, prior to which I had many years of Windows intuition. I literlally just started with using no fancy features or trying to be a Vim power-user, basically the only keybinds I used where i, w, q, and wq, I learnt dd organically, and have just been learning the odd trick here and there. I still use about 1% of Vim's total capacity, but I already vastly prefer it over Nano for features aside from those behind keybinds. I still turn on mouse mode on Vim, I still use the arrow keys rather than h/j/k/l, but it gets me through my day painlessly.
