Drowning in Housework

For the most part I am a pretty organized, "stay on top of it" type of person. This applies to my personal life, professional life, home life, etc. I get things done and I get them done pretty immediately. It's a standard I have pretty much set for myself. While others (bosses, husband, children, etc) hold me to a certain standard it comes no where close to the standard I hold for myself. Therein lies the problem.

I have been letting myself down and while for the most part it isn't that noticeable, it is driving me crazy. For example, I have a pile of laundry as tall as my two year old waiting in the hallway to be folded. I have a floor that hasn't been mopped in a week and bedrooms that haven't been vacuumed in that same amount of time. There are toys and magazines and library books in various spots throughout the house where they don't belong. My husband says he hasn't noticed (although, I know he is lying about the pile of laundry). While I know all these things need to get done I also just simply can't keep up. I feel like I clean one room only as another room is being systematically destroyed. I finish cleaning up the kitchen after breakfast just in time for it to get messy again for lunch and then dinner. I am constantly picking up toys.

These are minor things, I know. They aren't going to keep the world from spinning, but it seriously causes me great anxiety just knowing the house is not the way I like it and it's because I just can't keep up lately. So, I want some suggestions. How do you keep your house in order while keeping a firm grasp on your sanity? Is it possible?
