The amount of stuff that creeps into a home is astonishing. I was thinking of moving again recently, and then I basically replayed the last move in my head, and the pain came flooding back from my memories so intensely that I screwed that idea off immediately. I now have things like a pretty big bed, sofa, computer desk, bookcase, etc and so many small things that are hell to move.
I've got to be honest, I really miss just living in pre-furnished apartments. It was nice knowing that I could just up and leave relatively easily, whether it be to another place in the same city or another city entirely. Moving non-furniture items is pretty straightforward because at least you can do it in regular cars with family or whatever. Once you get into the realm of big furniture we're talking significant labour and the need for a van, plus it all has to be done in pretty much one go — no moving a bit at a time like I could when I just had general crap to move.
When I do next move, I might very well try to just offload all of my furniture. It's going to hold me back too much if I decide to move to London, abroad, etc.
