Organization is like a puzzle. I really think it is a trait that is determined by your brain and that some people's brains just don't work that way. An artist can look at something and draw/paint it and it's a treat to behold yet when I try, it's a stick person or a smiley face. Same thing with organizing for some people.
I am really good at organizing and have tried to help others who have asked for help to get that way. I have concluded that some people just don't see it. In the midst of it all, their eyes glaze over, they get this confused look on their faces and almost just freeze in place. When it's all finished, they're thrilled with the results but two weeks later, it's all back to what it was before.
My personal rules:
1. If you haven't used an item in a year, ditch it. I say a year because some things are seasonal.
2. Create designated zones. All kitchen items are in the same area, all clothes have a place, all tools together, you get the idea. And the zones should be where you would use the items. For instance, I dress in the rear of the van so that's where the clothes go.
3. Containers are acquired to fit certain items and/or spaces. Nothing else goes in it but what it was acquired for. I think the biggest mistake people make is to grab an item, look around and think, "Where will this fit?" And then just stash it. You'll never find it again. One must, instead, think, "This is a kitchen item. It goes IN the kitchen area. Period." There may be a very few exceptions (something too large to fit there), but mostly you must stick to your guns!
4. Whatever you do, it must be easy to use! If I have to "fight" with something to use it, it's gone or rearranged or changed.
It's my observation that people who just can't stay organized also tend to be very attached to their things. One lady had numerous kitchen gadgets that required lots of space to store. I asked her when was the last time she used that item. She said, "I haven't used it yet." Me: "When did you get it?" Her: "Oh, about a year ago." If the word "someday" is in your vocabulary (as in "someday I may need/want this"), you may want to consider getting rid of it.
Best of luck!
