This is a condition almost every house in America has, and the solution is fairly simple. This tends to arise when you move or sell your house or you just want to start over. What we all need to do every once in a while, is to de-clutter their life. It's quite common for many people to move stuff we don't really have to have to a new place.
Don't you feel that it is time to take all of the things that simply get hauled from one location to another, and get rid of them. Do you ever think about why it is difficult to get organized or to eliminate things? Is the disorder making you feel depressed and tired? You might want to set aside a day to de-clutter your life and see if a sensation of burden is lifted. You can certainly start off by identifying your stuff by contributions, storage, garbage and recycle.
Whatever that you may not use regularly, stuff you haven't touched for years, anything that you have been planning on fixing for longer than you can remember, put in one of the boxes. Should you run into things that you just can't get rid of, put in a box that you have labeled memories. Put the box away somewhere and revisit that box and decide if the stuff in there is something you really need. It is possible to take photographs of the things in your box so you can remember them but nonetheless dump the real stuff.
When you get things out of the way, be sure to pick-up everywhere you go. Take the time to keep your space clean, or the mess will start to pile up. Try to make it a habit to put away the things you use, right after you use them. Clearing a few things every day is easier than letting everything stack up, until you have another big mess to clean up. Mess stacks up every day, all the time, so you need to de-clutter the same way.
Make the effort to spend some time during the day to organize things and clear up. As we make it possible for things to start piling up, you will have massive clutter in no time. Although it might be challenging at first, but you'll start enjoying the clean organized space. While the mess is removed, you will feel as if a weight is lifted, and how much lighter you will feel. If this seems to be too big of a job, just begin with one room.
