I think teaching a temporary student is challenging for the karate instructor. In the dojo, there were several occasions when students wanted to learn karate but only had a limited amount of time. It may be a parent who wants their teenager to learn basic self-defense before heading off to college. It could be something a person has always wanted to learn but never had the time and are able to give it a few months. The temporary student is usually forthcoming about their time constraints. "I want to learn karate but I only have X time. How much can I learn in X?"
Tough question to answer.
Answer Option 1: You can learn a lot about karate in six months. It ultimately depends on how much time you commit to practice and study.
Answer Option 2: Karate is a lifetime of learning. The more you learn the more you recognize how much more there is to learn. Six months would barely scratch the surface.
Thoughts? How would you answer the question?
