One of the main concern of people in their homes, when they have time to look at it, is that it is very dirty, messy, dark or anything that is not good. That is because everyone gets busy and so cleaning and arranging things is not easy. If you have children then it adds to it as they also have many belongings like toys and they also want to play and things could get really disorganized and it could get to a point that living in it is hard.
That is why one of the tips that are given so that it will not reach that point is to do things when you looked at it. Even if you feel tired, if you will not do anything then it would add to the mess. The good thing to be done if you have children is to teach them to tidy up their things and help in making the house clean. If they are used to helping then it would be easier.
When you are cleaning one room, grab everything that is trash or if your collecting clothes for laundry then grab everything before proceeding to another room. You will use more energy when you go to one room and then another get small things. Get a basket and put it all there. Assign areas of storage for everything. When you do not know where to put one thing then it will just be put in one place that will add as a clutter.
