My wife and I are pretty new to this whole frugality/minimalism thing. Over the years, we have always had trouble keeping our house clean. It's not that it was dirty as much as it was cluttered. We just had stuff everywhere. But that kept us from being able to really clean deeply.
Last summer I decided I was going to re-roof my house on my own. (Stupid decision. I learned a lot, but mostly that I'm an idiot.) To do that, I called and had a 22' dumpster delivered to the drive. But while I was on top of the house pulling up shingles one-by-one (ouch), my wife looked at it and started throwing junk away. Stuff we'd had for 20 years that we didn't need or want. She threw away furniture, she threw away dishes, threw away old computer stuff. Just tons and tons of it. She threw away some stuff that I had thought about selling, but I was probably never going to get much money for it or actually get around to selling.
Between our household junk, our shingles and tar paper and some bad plywood, and our neighbors throwing some stuff in, we threw away 3.25 tons of junk. (I know, because we got charged for the overage)
Our house has never looked better. It still gets messy, but we have so much stuff out of the way that we can pick it up in an afternoon.
Could we have made money on some of the things she threw away? Yes. Maybe, all told, a couple of hundred dollars. I hated to throw that away, but it has made such a huge difference in the house that I feel like it was absolutely worth it.
Long story short: get a dumpster.
