You miss Monday’s step class, then move it into Wednesday’s diary beside the class already booked there. One unavailable evening has become two appointments to fit into the next.
I would start by closing the Monday booking. Mark it as missed, keep any useful note, and take it out of the list of things still waiting to happen.
Marking Monday as missed keeps the record honest. It leaves Wednesday open for a decision based on the week you actually have, instead of automatically carrying an old appointment forward.
Now look at the next class on its own terms. Does the time still work? Is it a session you want to attend? If Wednesday’s usual class fits, keep that booking without adding a second one just to restore the original count.
If you want to replace Monday’s session, give the replacement a current reason. Perhaps that class teaches a sequence you enjoy, or a different time now fits your week better. Choose it deliberately and check what else is already in the diary. A replacement is a new plan, with its own place in the week.
Then look at why the first booking failed. A meeting ran late. The journey took longer than expected. You booked an evening that was already crowded. Write down the practical detail rather than turning it into a verdict on your motivation.
Change one part of the arrangement that you control. That might mean allowing more travel time, choosing an earlier class, or making fewer advance bookings. These are options to consider, not a formula that guarantees attendance.
A week with several missed classes deserves a fresh look at the timetable. I would clear the old bookings and decide which sessions belong in the coming week, rather than carrying the entire list forward. If you follow a programme set by a coach, agree changes with them.
It is a principle I want to carry into MOTRA too: leave room for a plan to change.
Leave Monday in the history. Give Wednesday a reason of its own, and enough space in the diary to happen.
