The problem: When starting to clean your flat you find a lot of disorder
The reason: A lot of small things easily remain somewhere after you were using.
You might usually think: "I will bring them to their place when I have time" or "at the next possibility I will bring them back to their place".
The solution: When going from one room to another just look around if there is something that you can take with you to put in place.
Looking around what things might serve when brought to another room that you are going to or passing by and taking them with you gives additional value to each meter you are walking through your flat.
