If you aren't a routine kind of person, try the 10 minute cleaning method.
Go in a room and set a timer for 10 minutes. Speed clean for 10 minutes.
Go in the next room and do the same thing until you have cleaned all of the rooms in your house.
It may not be perfect but it will look a lot better than it did before!
You can even throw in 1 load of laundry each day.
