Your work feels routine most days, or if not routine, then at least manageable–to you. You know where the invoice slips are and that September is the month to book a venue for the spring retreat and who to send the worship bulletin to and by when. Once you’ve been at this awhile you’ve got the major blocks of your work in hand and it all flows like normal.
That’s the time to try to explain it to someone new.
The simple exercise of talking through the annual events calendar, for example, and describing why each event is on there, the major tasks required by each one, ways you changed events last year, and so on, is sufficient to remind you just how much is involved in all of this. You’re not conscious of it anymore, but the work you’re doing is complex and you have mastered major parts of it.
