*Proceed from higher to lower. Start upstairs and work your way downstairs; in general, clean higher places in each room before the lower.
*Proceed from dry to wet. Begin with dry rooms and areas without sinks, tubs, or toilets, then go on to wet rooms and areas.
*Proceed from inside the house to outside.
*Begin with the chores that require waiting periods. Start time-consuming automatic processes first - bed airing, laundry soaking, soup simmering - so that they can proceed while you do other things.
