Teacher's should care.

Yes. Martial Arts instructors should care as much about their students as they do their bottom line. With this hard economy it does get very difficult to think of anything but money but you're an instructor of an art that has been past down through countless generations.
You should be very mindfull of how your art is being taught and how your students are learning. Not everyone can learn in the same manner. There are those that learn by hands on, (like me) and those that can learn by reading and watching.
Take an interest in learning how your students are learning and decide the best way to teach them. If a student has a problem then show an interest in finding out what it is and helping them.
Remember....your students reflect you and your school and all the other instructors and students before them..
More on instructing ways later..until then....God Bless
