OK your pic made me feel a bit better
We tend to take 3 steps forward, 2 steps back -- but at least we're generally moving forward. Our house is in the best shape it's ever been, though there is still way more clutter than I'd like!!
Things that are helping us:
-Getting almost all my bills online
-Tossing out mail as soon as it enters the house (DH still needs help on this one... *sigh*)
-Dedicating a drawer of the desk to mail, since we don't yet have a good file system going & no money to buy what we need!
-Having a small basket for DS's 'junk' (small cheap toys/favors, paper-bag puppets, etc.) so he can play with it for a few weeks & then toss it when he tires of it
-Being brutal with keeping 'perfectly good' stuff... I try to sell it on CL first, if I can get a few bucks for it I feel better parting with it, or if I can donate it directly to someone who needs it, that helps too, but in general just keep donating/freecycling because many of those things are easily acquirable in the future should we need it... admittedly, this has gotten harder with DH laid off & me in a big crafting phase right now...
-Along with the previous point, keeping an eye on "wanted" ads on FC/CL... encourages me to get rid of things I might otherwise hang onto
-A place for everything... if we don't have a place for it, why? Do we need to get rid of the item, or do we need to find/buy/create something to store it properly? Even 'junk' should have a place if it's not something I'm willing to part with for whatever reason.
I don't know, that's all I can think of right now but maybe if you can elaborate on the type of clutter you're dealing with we can come up with more ideas!
