If you have some frustration or overwhelm with the scope of what might need attention in your home, my best advice is to pick one room and let yourself focus on that room.
Don't worry about the rest.
We're even applying this to the outside of our house.
We have 12 acres of work to do here on our property and thinking about it as a whole makes me want to light a match.
But if I section it off into outdoor "rooms" it feels much more manageable and changes everything: mostly, my attitude, energy and willingness to start.
