I have some house rules:
I have a trash can right by the front door -- all junk mail goes right into it, don't even think about carrying that stuff into the house and opening it.
I empty the dishwasher every morning and all the dirty dishes from the day go into there and not the sink.
If you don't have time to fold the laundry and put it away, then please don't bother to wash it. With 5 people in the family, laundry can pile up in baskets like you wouldn't believe.
I wipe down the bathrooms every morning after I'm done showering. It only takes a couple of minutes.
We are a family that collects "stuff" like crazy. I keep a large Goodwill box in one of the closets and when something becomes unlikely to be used often enough to make it worthwhile, it goes in there. When it gets full, DH drops it off at the collection center. When space is at a premium, there just isn't much room for stuff.
The kids have folders on the bookcase that they put all the graded papers they need to keep in. If they don't put it in there, it gets thrown away. Graded schoolwork can pile up fast.
About the only thing I ever got from Flylady was the sink needs to be clean every night. That forces me to wash the pots and pans and put them away.
