After the UBG, what would you recommend reading next?

[Jared G.]

I have read the Ultimate Beginner's Guide a few times now. Obviously, this site has tons of articles, blogs, podcasts, and other information. If I am looking to buy and hold SFRs and/or multiplexes as a complete beginner, what are the next best books or articles to continue learning?

I am feeling completely overwhelmed by the amount of information out there.
