Our house is now as clean as it has ever been since I've lived here. We have a functioning office area. The kitchen makes me happy, the coffee table -- for God's sake -- is clear!
We do have a spare room, that we call the "red room," which, along with the garage, are areas for us to sweep things under the rug, so to speak, but life is still so much better being able to walk through the house with out my eyes having to dart away from clutter here, clutter everywhere.
Investing time here should pay off during the school year.
