After failing miserably I decided I needed to learn a whole lot more about computer and systems architecture before I could actually nail them, and that's what I am doing right now in a certainly chaotic way, but I think I'll eventually get there.

Yeah, you will. All I'm managing on my own are easy to medium boxes, but I learned a lot. I found one book to be kinda helpful - even though it's outdated technology wise - and that is georgia weidmans 'penetration testing - a hands on introduction to hacking'.
Have fun learning - hack the planet!
