Are you organized?
I like the idea of being organised if that counts! I think I am mostly with the exception of home paperwork which is currently sitting out on the lounge floor waiting for me to go through everything again. It's been there for several months
How often do you purge your closet/drawers/cupboards?
I had to do a major purge when I got divorced (3-4 years ago) as my current home is probably a third of the size the family home was, compounded that I no longer have a garage or shed and still have to have the loft boarded. My only storage space as such is the small area under the stairs. There are a few things I'm wishing I'd kept though. I've been pretty good at not buying new stuff just because, well there is nowhere for it to go!
Do you keep things "just in case" you might use them again?
Small things that fit in cupboard or drawer I would say yes, but nothing larger. Again. Space. And before this was defiintely yes. When we moved, we had a couple of skipfuls of stuff, many bonfires, trips to the charity shops and to the tip. My ex was the biggest hoarder. He worked in the building trade and our double garage and huge workshop were filled with his stuff.
