1. Followthrough - To me this means completing the action. You bring a dirty dish into the kitchen, if the dishwasher is dirty it goes in there and not onto the counter. Go shopping, put everything away when you get home. Have something that goes in the trash or the recycling, put it directly into the trash or the recycling. Going downstairs, take something that is upstairs and belongs downstairs and bring it downstairs (see point 1 if it's a dirty dish).
2. Do a chore before doing something for yourself - The idea is this, if I have some baby-free time for myself, do a chore (or half of a chore) before taking the time to do what I want to do. Just 5 minutes of doing dishes or folding some laundry before playing on the computer or reading or whatever should really help us keep on top of things.
Hopefully by developing these habits, Aerith and I can keep the house in a state where we are both happy with it.
