My husband and I discuss our schedule for the next day the previous night: who has the car, what time our meetings are, who needs to take on a responsibility the other can't attend to. But by morning, with so much going on, he would forget what we'd discussed, and we'd repeat the conversation. This happened to me too.
Here's how we solved it: he retains information by writing it down, using post-its and a calendar. So do I. All we did was share our calendars, meetings, organizing sessions, personal appointments, consultations, networking, volunteer work, reminders, everything goes on the calendar. We know who's busy when. We still discuss our agenda before bed, but we also check each other's calendar when we start the day. Life is comparatively simpler now.
