I am dreadful for hanging onto clutter. I think it comes from being brought up only getting things for Christmas and birthdays. If something got lost or broken, too bad - you still had to wait to get it replaced, and that has stayed with me.
Also, I was taught at an early age that you should 'buy things to last', which doesn't really fit with today's society, where things become unusable, rather than simply out of date. I'm thinking of things like the enormous number of DVDs we have, despite the fact that we tend to stream films, and know that before long it will be impossible to buy a DVD player if ours breaks or wears out.
I now have an 'it might come in useful one day' mentality that is very hard to shift, and I have so much 'stuff' after living here for many years that it's getting on my nerves. It's not remotely on a 'Hoarder Next Door' level, but bad enough to make me realise that I need to have a massive clearout, which won't be easy.
It's annoying that at the very time when we could be getting on top of it all there is no way to get rid of it all, but obviously there are good reasons for that.
In many ways, I would love someone to come in (when I am out and unable to make contact in any way!) and do the clearcut for me, so that I don't get too upset at the thought of throwing things away. I'm quite sure I wouldn't miss 99% of it, and the other 1% could easily be replaced.
