I can relate… If it is worth doing, it must be done 100% right, first try, zero margin for error, no rehearsals, no practise round.
Like rocket science!
(Except I know that’s not how rocket science is done, either, but somehow that thought refuses to sink in)
Even for the simpler stuff, it helps with the teaching process to be able to hone in on where the specific misunderstanding is. Or if mistakes are being made, slowing down a bit to correct the process can help.
