Your job, for day one, is to find your focal point. What is the one thing in your house that if it is not done, will absolutes make you feel like your house is a mess? Like, if every other part of your house was a mess, but this one thing wasn’t done, your house would still feel messy? Whatever it is, that is your focal point. So that is the first thing that you need to do. That is day one.
If you feel like you can do more than one day at a time, that is wonderful! Go right ahead.
