Rather than leave another long reply to read, I’ll leave my thoughts simple: if you have another computer you’re not using, try Linux mint and see if it fits your needs. If it’s too much and you can’t get the time needed to figure things out, 11 might be the choice (for now).
But either way, keep Linux on the second and learn a little bit as you get time to! :)
Add
PATH="${PATH}:~/.local/bin"To your .zhrc or .bashrc (whatever you use) and either source the file or open a new terminal. Should be as simple as that (assuming +x permissions)
