This lifehacker article about Personal Inventory Day makes a bit of sense. The gist is to take a week every month to reset and make sure things are going in the right direction.
I’m not sure formalize it this myself, but I do make a point to get an espresso on Friday mornings to square up and make sure things are pointing in the right direction for the last workday of the week and the weekend. Maybe I should also use it to just assess things in general.
