Remember the law of the home: Junk expands to fill the space available, plus one room.
Preventive Maintenance: Don't start today by doing yesterday's work.
Even an organized person has days that aren't efficient and well-managed.
I have been housekeeping for 31 years and I learned something new on every page!
Work at getting organized like a hobby. Set aside a certain amount of time each day (or whatever time your budget will allow). While it may indeed take a fair amount of time to establish order, once it is achieved, you will save more time than you have ever spent.
Decluttering tip: Ask yourself do I need this? How long has it been since I used this? Do I need so many?
