Teaching is also a talent. Much like in singing or dancing there are people who excel in teaching, because they not only use the correct methods, but also manage to improve them, or adapt to circumstances when necessary. Very few people are capable of that, and you cannot train that. The problem is that there are teachers who do not want to teach at all. And those who want to teach are rare, and those excelling at teaching are as rare as people like Richard Feynman.
