persephonevii, I too live in a very cluttered home.
It did start with my family and I remember when I was very young that clutter was never a problem but when some bad events began occurring things started to get cluttered, fast. I do recall us going from very rich to extremely poor. Clutter wasn't the main reason for it, but it certainly didn't help our situation.
The inside of my mother's house, last I remember it, could have passed for a village's dump. Seriously. Even the backyard was a mess and no matter how much I cleaned it up, the next week it'd be right back where it was.
I will not go further into details here as I don't want anyone to lose their lunch.
So I gave up with trying to clean and gave in with the rest of the family by just ignoring it.
I still live in clutter but no where near the mess I did when I lived with my mother as a kid. I made a promise to myself that I'd never allow clutter to get THAT bad again in my own life. In my home there may be paper all over my desk, clothes on my bedroom floor, and dust on items but that's about the worst of it.
Yet, recently I've really taken a critical eye on this (your post has helped somewhat) and have decided that I'm going to keep a less cluttered home and life.
I don't live in poverty anymore but I still waste a lot of energy trying to find what I need. In a sense, that causes me to lose out on opportunities [and money] because I could not find that phone number fast enough, missed an appointment for a fun event because I lost my planner, and so on.
So I'll be going harder on myself this summer to clear out unwanted items. I may even go as far as to throw out what I won't be using for the next 3 months (minus seasonal items.)
I'd honestly rather have less around me now, to make more room for opportunity, than have more of a past that only burdens me now.
