If you want access to it at system-level, you can use pip install --user ...
. If you run scripts as your user it’ll be as if it was installed as a system package.
Only use that if it’s something you use to manage your system. If you’re using this as a development environment, use venvs.
Honestly, this is it. You have to want it, and you just have to do it. You’ll feel “sick” for a while but you just have to muscle that out.
I know it’s easier said than done, but it really is that simple. Just stop.
