To better one life is to better the world. - Alan Shaw Feinstein
I remember when in the 60's and early 70's karate was taught as a process of elimination. Instructors tried to run people off and then make black belts out of what was left. A new class of beginners started and the process continued.
Now we try to empower each student and help them become all they can. Starting with belief in themselves. And a can do attitude. Even bits of leadership is taught. After all everyone is a leader and the most important one you are leading is yourself.
