hello, idk ... i would heavily recommend: try to read stuff, its much more efficient than watching videos -> eg. time vs information. additionally texts can - and must - be consumed in a non-linear fashion: go back & forth, mark stuff, read excerpts, follow references etc. and imho. get your "feet wet" - books / articles / courses / theory is great, but especially in (linux) system-administration most things are acquired by doing stuff / solving problems / getting in contact with the "real" world ... and if its only in the sandbox of your home-network behind some router... consume howtos / tutorials & follow the references to fundamentals. your knowledge will get broader over time and fundamentals always pay off, but you can't learn it all at once from the start :) for example: DNS is the basis of all services in a network. learning how it works and following best-practices pays off not just multiple but a 100 times the time invested to wrap your head around it ;)) just my 0.02€
