I heard somewhere that the biggest temptation of the artist is to try to reproduce her work. That is probably because inspiration can’t be cloned as per some formula.
I try to keep that idea in mind when working with comprehensible input. I accept that every class will be different, and that there will be very few really good classes. I don’t try to repeat a previous class’ success in the next. The universe won’t let me do that. CI is not a stamped kind of product that one can duplicate.
