I want to do a blog post series on this topic. Systems administration is a huge topic with so many interconnected parts and such vast variety of tools. Even breaking it down to segments can fall apart easily as nearly all topics overlap from user management, to filesystems, etc. My only advice is this: Get a copy of "UNIX and Linux System Administration Handbook" and read the topics that you work on. It's a reference not something that you can read from cover to cover, but it's I own the 4th edition and it's depth is amazing. On 18 Aug there is the 5th edition coming out. Grab a copy. My only issue is that I'd love to have *BSD included along Linux, Solaris and AIX (which is hard to find these days...).
