I don't multitask often... mainly because I don't have that much to do. I do have areas for certain tasks, bathroom for showering and cleaning the old pipes, kitchen for cooking, living room for computer,tv and it's also my dining room. oh, and great for naps too. I must admit I don't dust often, that when when I move something, I know where to put it back!
As to changing my environment, I just call that a vacation!
