I just had a moment where I downsized my RPG book collection. Do you ever weed out your collection? I find myself becoming a bit of a headless chicken, sometimes more interested in what the promise is that a book might hold, rather than diving in deep into the ones I already have. This superficial engagement with many books I find very unsatisfying. The books I cherish most are the ones that I have really sunk my teeth into, and I have a feeling that there is still a lot to discover in some of those that I haven't revisited in a while. Master the tools you have, rather than acquiring ever more barely used tools. Just wanted to air my thoughts, quite happy right now with my smaller collection of things I really cherish.
That's tough for me because I love collecting and reading rpg books. Yes, I'm incredibly boring. I have numerous books from different genres, and many editions of some of those. The older the series, the more interested I am in acquiring and reading it. There are some that I have read through repeatedly; like my Pathfinder 1e CRB. Others have gotten one solid read through followed by occasional perusing. I get the reasoning that too many is just too many to deal with, but I've just come to accept that this is my hobby now.
