I started at the command line, it was basically all there was for me as I didn't have internet access until much later, & that was via a modem.
Basically, you just need to try things, read the man pages, & experiment.
You'll probably get good at re installing, as you mess around with the system, but it does teach you what not to do. Learn by your mistakes is how I got where I'm at, in the main, with some help from others at times.
The time to ask questions is when you can't find the answers after reading man pages, checking books, looking online, then people will willingly assist you. Enjoy the journey.
