You know you probably ought to start cleaning soon, but you just lose energy thinking about where to begin? I've heard of the "room" approach to cleaning, and the "task" approach to cleaning. With the room approach, you start with the dusting and vacuuming. Then you pick everything up and maybe dust and vacuum again. What I find is that this multiplies my task sometimes though. It would force me to make 50 trips to other rooms with "wayward" stuff. The task approach is best for a quick touch-up, though I must admit the results aren't as tidy as the "room" approach.
