I hated languages in school because besides grammar and word mistakes, grading always felt arbitrary. However, that teacher recognized that I struggled, gave me a generalized template and said "If you do it like that, you get a good grade". I did it like that and got a good grade (we have 1 (perfect) - 6 (trash) and I improved from 4- to 2+ which is quite a big leap). So yea, that was the first time that I perceived that subject and a teacher of that subject as something real and not bs.
