Being a single parent, owning a business and having kids involved in activities, our life could get a bit hectic. We had a white board calendar in the hallway with all the 'stuff' listed on it (the rule being that if it wasn't on the board, my car didn't go there!). Every once in awhile I took the marker and put a giant X thru a day. That was our 'non-day'. No schedule, no plan, nothing. If you didn't even want to get out of pajamas - fine, wanted to lay out in the yard all day - fine, want friends over to play - fine, Just nothing planned, scheduled or time driven. It was great! We actually started 'scheduling' more of the non-days as they got older. They are all grown and on their own, but we still have the practice of 'non-days'.
