Rubber maid

I have spent the last few months accumulating rubber storage boxes so that I can de- clutter our house and literally leave the minimum amount of 'stuff' in our living space. I guess kids make enough mess as it is so piles of junk is not what I need.
These tubs have made for great storage solution because I can label and stack without worrying about the damp. I think I have about 20 boxes down in the basement (it's horrifyingly to think that we have accumulated that much junk)
I can't understand that even with all my storing away the house still gets in a mess and I'm constantly tidying?
