I've been watching anime for a very long time but I don't much anymore. Well, scratch that, I actually still watch anime quite a bit compared to a normie, but definitely not as much as some people here, and also not as much as I used to. I mostly follow older properties I've gotten attached to, but if something newer seems fun or interesting I may check it out. That just doesn't happen as much anymore, especially as I prioritize my time for other things, but hey, I still like anime. If something was enjoyable the first time, I think it's worth rewatching. I'm more likely to rewatch old favs than put the time into something unknown.
My list is definitely not a rec list and includes stuff I don't even remember watching, what I remember watching but not many details about, anime I wonder why I watched in the first place... Though my favs are still there as well. I don't take rating that seriously and just put what I think seems right at the time, then don't think about it much later.
I try to make my anime list complete, but my manga list is far from as I've read a lot of things, then forgot, read random volumes from the library, etc. I'll probably just add to it from here than try and remember everything I've read.
