I really evaluate my weeks ahead of time. For the most part I follow it as listed, but rooms may get switched around according to my schedule and what's on the calendar for that week.
When the week comes, I'll note when I have time available and fill out my to do list. Mentally I think which days will work best for what and just start checking down the list. I do the most needed task first and if I don't get done with my list, I just a leave it blank. If another week comes and I have some time open, I'll go back to unfinished items on the list and do them. If I don't, I don't.
Take time to do the mental image around the room. Ceiling to floor, what needs to be done. I just sit in the room, start on one end and work my way around to the other and write things down as I go. if I think of something else later I write it down. I've also kept my list from last year, so I can see if I've forgotten something or have something on there I don't need to do this time around.
Mrs. Clause is right. Tackle the project with Joy! If I don't have music on, I'll watch my favorite show while I work. I get to watch tv, but don't feel like a blob. I'm an expert at commercial cleaning too! You'd be amazed at how much you can get done during commercials for a 1 hour show. Then if you watch any reality shows like me (maybe DWTS), then you know there are ALOT of commercials. I'll wash dishes in between, clean the toilet, take out the trash. Whatever I can think of!
I also tell my husband at the begining of the week what zone I'm in and what little fixes I'd like him to do. Sometimes they get done, sometimes they don't. But if not, I'll ask again on the next go around.
Most of all, it's not about being perfect. Just remember..SOME IS BETTER THEN NONE!
