What is the equivalent to Winter Doldrums?

O.K. I feel like I have hit a wall. I have a ton of projects on the list and none of them are getting completed. Not to mention, the mess the house is in. Looking for suggestions to jump start my motivation to get/keep this house in the shape I like. Kids are pretty much doing their part, it is more my lack of energy to do the everyday stuff. What do you guys do when you hit this sort of slump?
