Most of your stuff you won’t remember having it, or where it is if your looking for it, and probably would never set eyes on it unless you were moving or had to create space ( another room etc) I was the same until I had to down size and so had to get rid, which I’ve done 3 times now. Bear in mind I bought more things over the years, gadgets etc, so it accumulated again. Final and deciding factor was when my son said he didn’t want ANY of our stuff, photos , crystal and lots of things which I geeky were not only sentimental but if good quality and value, and even photographs. So I got ruthless and got rid of the lot, apart from the photos. I then got a lot of the framed photos which don’t suit my decor in our house and put them up in the walls in our garage, so I see them almost daily. I haven’t regretted getting rid of anything. Gave it all away to friends and charity, I now know what’s in our house, and most of the time remember where it is, and is being used even if it’s only twice yearly. Decluttering majes life easier for you now, and your family later. I’ve kept a small box of mementoes.
