So kinda dark, but a few years back my grandparents passed and I had to help my family clean out the house they lived in for 40 years. My grandma had OCD as well which contributed to her keeping a lot of things. Cleaning out their house really helped me become better about keeping/tossing things. I find that if something is really that sentimental I’ll have it displayed or actually use it on a daily basis. If it’s something that I keep because it’s sentimental but I keep it tucked away in a chest or a box or something like that then it isn’t worth keeping and cluttering my house. I still struggle with having too much stuff but seeing how many unnecessary things my grandparents kept around that they never used or was hidden behind other things they had piled up and then having to clean all that out for three months made me realize that it is not worth keeping everything I own around. I also just moved out of my apartment and having to pack up everything I owned there, because I had a lot of stuff, was exhausting and took a lot of time. So maybe think of things in a way that if you had to move would it be worth packing up and taking with you. That helped me make a few last minute decisions as my energy was starting to run low as I packed. Hope this helps!
Wow thanks for the reply. I’m actually moving to that’s why I have to declutter.
I have a great bit of organizing advice to pass along. Doesn't work for every sentimental item, but you can take photos of some things before you get rid of them. Then you keep the memory, but discard the item you don't need. If it looks weird in a photo, take the photo holding/using it yourself.
