i have been doing Linux for 22 years and know it in and out for the most part and you never stop copying and pasting. sometimes I know it fully and still copy and paste out of pure laziness for longer one liners. but best advice I can give is. Don’t ever feel like your not good at Linux case you use a DE vs window manager. or use one distro vs another. There is some gatekeeping people do just like with any hobby/community. Just ignore them and enjoy learning something new.
Trust me, you will miss the wonder of learning and playing with a new interface and ways of doing things. its funny I go the other way now loading up windows 3.1 in DOSbox just to play and try and remember how to do things and get things working.
