Thanks. Learning from experience is way more fun as you wote.Welcome to Linux.org.
I'd say be patient and you'll learn as you go. There are books, videos, help sites, and things like that. However, you can just learn as you go. When you need to do something and you don't know how, you can try for yourself or you can use a search engine and learn things as you need to learn them.
I've done a bit of both, with a number of Linux books in my collection. I find the stuff I learned as I needed it to be better understood than the theoretical stuff I've picked up in books. I also can't stand video content. No, I will not click on your video.
Anyhow, we're a pretty relaxed bunch here - with hundreds of years (combined, with just the regulars) of Linux experience. If you're patient, someone here can almost always get you squared away.
