There are really two parts to organizing any space. The first is to declutter and organize the space and contents and the second is to keep it organized. When figuring out how to organize any space, solutions need to fit. It needs to feel right for you. You know whether or not you are likely to keep up a particular solution. One solution might be a better fit over another. For example, if you often misplace your car keys, do you think you can keep up with a solution of putting them in the same spot every time you come into your home? Or does putting them in the side pocket of your car door seem like a better solution? You know what will work best for you.
The second part is maintenance. Keeping up with the solution. Making it a habit. Once you designate a spot for your keys or (fill in the blank) you have to put your things away! I say that a lot in our house! It’s much easier to put things away when you know where they belong so just do it. Make it a habit to put things away and encourage family members to do the same. When you are going upstairs, don’t walk empty handed, take some things with you that you know belong upstairs. It takes discipline to maintain an organized space.
