Just get every piece of paper in a folder. Label them 1 to 31. Put every piece of paper in the day that requires action. Put it in the folder that's two days prior to when you can still register with a discount. You've been told to handle any piece of paper only once.
Pressure drains energy.
If you can't decide on a disposition, put a checkmark on the top of the paper and put it in the 1 to 31 file for several days later. Three checkmarks means throw it away. Move the stuff from the cardboard work file into the 1 to 31 folders. Start each day with a review of that day's folder. When you have to be in one, request an agenda and an expected end time.
