Its an imaginary teacher that only has to say it once. LOL I would go so far as to say that all teachers of the martial arts are missing something.Do you think pointing that out once is enough? This is the kind of thing that students need over and over and over. It's a very rare student who can learn something once, do it perfectly, and never need corrections again. Most students need constant reminders over a long period of time.
I think that is what most students do not get. I think they do not get it because their instructors did not get it, and do not understand it themselves, and therefor cannot teach it. I think that a lot of people who are "teachers" should not be teaching.
