If I have 1 regret from my years of teaching, it is that I did not cancel enough classes. My loyalty to the people who came was personal not professional and they would have continued to come, even and perhaps especially if I had been more business like in my class planning. My loyalty to the clubs where I taught was never reciprocated or rewarded, it was expected and that is a massive ask! Sometimes we have nothing to give and at these times we should be able to recoup and relax. You may throw in the need to earn money at this point, but in all honesty, if you do this job well, with planning and some percentage of a business mind, your days away from teaching should not impact your overall income.
