Neat person or not, decluttering is so much of the solution!
Less stuff=less crap that needs cleaning/organizing/schlepping around.
Watching this thread, I'm thinking that there is definitely some variation from one household to the next as to what constitues clutter. In our house, books are not negotiable, so building a huge bookcase was one of the first things we did when we bought our house. (Now that we've outgrown it, though, decluttering is about culling the ones we don't need so that the best ones all fit on the shelves...)
Cloth diapers were not a problem. We had a system, and it worked. Same with mama cloth. (I also use cloth wipes myself for pee for 3/4 of the month

but that's
only me, so it works out fine- anything beyond that would not work so we don't try)
Luckily it's easy giving away stuff here- we have to truck our trash and recycling ourselves, so we always bring along boxes of books and toys and kitchen gadgets and ____, and bags of clothes and sheets and blankets and towels and _____ to drop off in the free room whenever we go. I always have an empty box downstairs, and a bag upstairs, ready for stuff so that whenever I find myself holding something that could leave the house, I can take a few steps and shove it into the bag- and never look back again! Back when we were really snowed in with stuff (MIL sold her house and swamped us with a tsunami of brickabrack) I had one of those cheap plastic shopping bags on
every doorknob in the house. They filled up quickly, once it became so easy to cull stuff from the piles everywhere.
I'm shivering thinking about Christmas coming up. In DH's huge family, it's all about junky quantity over quality. It has gotten better very gradually, but by this time of year, we're scrambling to come up with ideas to suggest when they ask us what the kids would like for Christmas (and DD's birthday very soon) We'd love a bunch of museum memberships, but everybody wants to have something fun
wrapped in a box that they can watch the kids unwrap. I can't blame them, I just feel badly for my kids overwhelmed with stuff. They can't help but get attached to stuff, but then they drown in the massive volume of it all. Luckily my younger fella is pretty open to letting go of toys and clothes. It's time for yet another purge.
Just wanted to give a

to the poster whose DP is messy- that's us!
I like things organized. Not bleached-scrubbed-sterile, but reasonably organized.
Comfy dignity is all I ask for.
DH, on the other hand, is worse than a #$% teenager/puppy/tornado. After ten years of marriage, I'm having a very hard time keeping my motivation to carry out 95% of this work. The house has been a wreck for a couple of years, and I think the mess is actually worse for my mental health than the single-handed cleaning was. So now I'm trying to dig out of it, and the job is incredibly daunting. I try to pick tiny areas and do them one at a time. We homeschool, so I have plenty of chances, in small doses, throughout the day. I pick one drawer, and sometimes that one drawer takes all day (in the small doses) I pick one part of a big desktop, and set the tone for where future stuff will go for that area. It's happening in tiny baby steps, but any progress feels better than none.
Also, we do better with the whole nag/resist/nag/lash-out cycle when we give jobs a schedule. We made the schedule together, and now certain things happen on certain days of the week. Sometimes we kick butt, sometimes we only make small gains, but at least we're sharing the work (and the kids too) and spending energy improving things rather than bickering with each other
