Yes, I agree with the others who say it's an executive functioning problem. I don't thing all aspies have that so much, or that it's a requirement for being an aspie, but it seems to go along with the territory often.
I would LOVE to have my life and my surroundings more organized. I just don't have the skills to manage it, especially since I share my life and house with people who have their own problems keeping organized, in a house that is a bit too small. I could spend my entire existence doing nothing but trying to organize things, and it would still be a chaotic mess. Even when I've lived in situations where I hardly own anything at all, it's hard to keep it organized. If you look at books and magazine articles about organizing things, they always make the assumption that you don't USE your stuff. That you just want to store it neatly in the top of your closet. In my family, we use our stuff ALL the time. People have hobbies and projects, and it all takes up space which we don't have. You can spend all day packing things up in pretty, expensive Pottery Barn baskets, but there's no point, if you actually use the stuff that you own.
People who are naturally good at organizing things and keeping things tidy do not understand people who have trouble with that stuff, and tend to think that if you really wanted to, you could.
