In education, it is my experience that those lessons which we learn from teachers who are not just good, but who also show affection for the student, go deep into our minds. Lessons from other sorts of teachers may not. Although you may be compelled to study and may fear the teacher, the lessons may not sink in. Much depends on the affection from the teacher.
