Difficulty is about 1 of 5 for me so I guess I’m not too bad at this 
I’m sure you’ll be the judge of this at a later date, lol.
I’m glad I looked it up and then asked the questions about installing, for instance–I decided not install GNOME or MATE because of the version of this ISO–it came equipped via lightdm because of cinnamon, right? I’m worried about the dependencies since Cinnamon = GNOME fork, so something could probably overlap in the dependencies, I would think… That brings me to a question I have. Maybe I’m just over-analyzing this, but why did I have to create a different user for the separate DE I installed?
Why can’t I use my normal username, in theory? Is this new user a precaution or is it a 100% requirement? If so, I just want to know why, really. It was the very first thing I did.
