Problems with completion

With just about everything in life I get 95% finished and then I'm done with whatever it is. I don't know if it is that my head has moved on to the next thing, or I let myself believe that I am finished or maybe both? At any rate... I'm pretty sure this is part of my ADD and it is causing problems especially since I am currently a stay at home mom. The house is my job and with my inability to finish things I am horrible at it. It's causing depression in me and frustration/resentment in my DH.

All of this to ask... What do you do to make sure that you finish household tasks?
