Does your collection follow a blueprint?

Just wondering if anybody else follows a blueprint (I hope thats the right word?) for his/her collection.

I have actually 3 collections, one is keeping me on my toes.

First I used to try to collect every Doors record there is. I had already quite a collection, when I found this book here https://www.amazon.de/Doors-Rainer-Moddemann/dp/3893659277/ and tried to find all of the versions. I gave this up after I met a guy who had 5x more than I did - he was already 10 years longer in thet addiction then I was. BTW he's a nice guy, we are in contact regularly and in the meantime we both have changed our interests. Today I own 350 Doors records.
Plus 4-Tracks plus 8 tracks cartridges, about 50+ singles and a ton of books about the Doors in english, geman, french italian and even hungarian (which I don't speak)... ;-)

Second I try to physically own the 500 records according to the 2004 Book form Rolling Stone: The 500 Greatest Albums Of All Time - https://www.amazon.com.au/500-Greatest-Albums-All-Time/dp/1932958614 - I am still doing this, and to make it extra difficult, I try to get the first pressing from the country where the artist is from.
This doesn't work without compromises. When I had a better job, I enjoyed buying Led Zeppelins first for 2000$ (yes, the one with the misprint), but I can't afford to do this anymore. Also the Reggae albums don't come cheap with "Made in Jamaica".
I'm now around 330 records, 80% are indeed strict to the rule, the others are compromises, reprints, remasters, MSFL etc.

Third is "MY" collection, which doesn't follow any rule. Those are the records I buy because I like them, and of course I listen to those the most. Another 500 roughly and no urge to "complete", Jazz, Funk, Rock, even Chansons.

I keep track of all of them on Discogs, some I sell, some I wouldn't. Music has become cheap and portable, but I love owning the physical large record. It gives me joy to put them on the turntable.

How do you collect?
