Good enough should definitely be the mantra.
I think the trouble with teaching is that we are viewed by MN as moaners , but actually, because we teach, we are very biddable, rules driven, obedient people, generally who thrive on instruction and routine.
Therefore, we tend not to raise issues as this is viewed as disruptive and we are told , more or less, to put up or shut up, so we rant on MN, and it can all become a bit fraught.
fwiw, I think you are misreading crafty, kate.
What are you doing when you leave your current job btw? I have seen some of your other threads about getting out altogether?
