Is it normal that i keep track of many different things and tag everything?

Wow, I'm a lot like that. I don't tag all my files but I do keep lists of stuff like that. Actually most of those lists you've described I have too. I guess it's like OCD that I can't stand having fragmentary bits of information all scattered around in my head, I have to set it all down in a text document and organise it all.

I think it's also because I fear forgetting and forever losing that information. Like I didn't intentionally start making a list of films I want to watch. I just wrote down a couple films I've heard of that sound interesting and that I wanted to check out, just in case I'd forget the name of them. Then I added a few more, then a few more, and it turned into a list.

That fear of forgetting reason also makes sense since I also like to make comprehensive notes of anything I learn. I sometimes just randomly get really into learning about some specific random topic, and when I do I'll have to make lots of notes about it.

I've never thought it was normal though tbh, I've always felt like a bit of a freak for it tbh.

I do that too

YES!!!

OMG, I thought I was the only one who did this, lol!

I have always loved filling out Excel spreadsheets of multiple lists like this, mostly experiences, an inventory of one of my collections, etc. I love sorting it in all sorts of different ways and listing out characteristics! It is almost like a puzzle to me. I like to play around with sorting and listing this information in different ways.

I used to always fill out all of the details in my music like you describe on my computer as well (probably will again once I get my computer fixed)!

One of my music libraries is organized in folders sorted by decade, then by year, then by band/artist.

I even compile lists in my brain at random times, usually when bored or waiting on something!

With my collection, I will organize it by exact item, then list brands, parent companies of said brands, countries of manufacture (even the exact factories where applicable), the year I acquired each item (and the year of manufacture where applicable). Same with type of design, size, etc. I have a HUGE inventory all in my head that I can list off at any given moment!

I also rode horses for over 20 years and can list every horse I remember riding, and many details about them. Registered/show names, dates of birth, color, breed, partial pedigrees, etc. I also have that database in my head!

As far as OCD goes, I'm not sure if you or I either one have it, but I see this as a harmless hobby (and pretty fun for me) and say if it's not hurting yourself or anyone else, it's nothing to worry about!

Man I wish I had a computer to compile and organize information. I'm using notepads, let's just say it's tried but not true
