@Huma0Being a minimalist myself, I've noticed that hoarding is a really hard disease to cure 🙂
Everywhere I go, I'm amazed at the amount of STUFF people have. I'm happiest when I'm getting rid of things, rather than accumulating them.
Yes, it all might come in handy one day, but it feels so good to get rid of things that you really don't use. I guess you have to decide if it's more important to have the security of not getting rid of things that you might make use of some nebulous day in the future, vs being able to enjoy a clutter free space.
My rule of thumb is if I haven't used it, or worn it in a year or two, it gets chucked. Also, if you come home with a bag full of things you just couldn't resist buying (whether it cost a small fortune or you found it second-hand for next to nothing), make sure you bag up the same quantity of stuff to pass on or throw out that same day.
Most women I know have closets crammed with clothes, half of which they never wear. There's those things that you love the look of, love it when it's on the hangar, but when you put it on, you end up changing an hour later because it's just not you somehow. Give it away or take it to the consignment store, rather than putting it back on the hangar.
My ex boyfriend had a huge pile of building materials, pvc and metalpipe, fencing, etc. etc. that he refused to get rid of because it was all useful stuff. yet when he was in the middle of a project, that thing he knew he had was buried so deep in the pile and he just wanted to get on with the project, that he usually ended up going out and buying more.
I was staying with friends, went around and gathered up all the coffee mugs I found in the greenhouse, the garden, the shed, etc. and washed them all. They had 55 coffee mugs!
If you just can't get rid of stuff, get some plastic totes, organize all the stuff, and label the boxes. Go through it once a year and re-assess what you really want to keep. If after a year, you find you need to buy more totes, you're in trouble.
