Do you manage more than one person? Do you manage a family? How do you communicate your schedule of events to each other? Does dad know when soccer practice is? What time does that birthday party start?
Have a central message board for your family where they can post their reminders of upcoming events, schedules and notes. Ask everyone to post any information on upcoming or current activities. This will give you a central place that everyone can refer to and where that type of paper will live until it’s no longer needed. Make you message board accessible. Place it in the kitchen or near your usual exit door.
