Welcome
@super_user_do to the forum!
I read somewhere that Linux is not hard to learn. The problem is that it is so vast.
I think that came from William Shotts in his book about the command line.
It will be a life-long journey for those interested, as there are always some new things to learn.
One of the great things about Linux is that you can pick and choose to learn whatever topic is of interest to you.
A few years ago I decided to spend some time learning a little bit about C Programming. After that I spent more time to see what Scripting is like. I am not a programmer but am a little familiar with the terminology, enough to read simple programs' source code.
I'm 87 years old and will continue on my Linux journey as long as I can still read and use a computers.
Enjoy your Linux ride, my friend!
