Hi matt
It is not something you will learn in a weekend, or in school in 3 months. In my opinion you are in a good place to learn, better than many.
You can install ubuntu, mint, or manjaro, and not really learn anything for years, but if you really like to learn obarun is a good place.
This may be a good place to start
