He who has something to teach and wants to teach needs to understand that, in order to make his desire a reality, there must also be someone who wants to learn. This is a fact: the best teacher is not able to overcome some of the barriers that a bad student can put up; a good student, on the other hand, is able to learn something even from the worst teacher. From this we can see that learning, in short, depends more on the student than on the teacher, who is limited to facilitating or hindering learning, stimulating or discouraging. This is the case no matter how great the teacher’s will or knowledge.
