When I teach introductory classes I like to teach the concept of courage
to new students.  Many children, teens and adults come in with
courage already.   You need a little courage and humility
in starting a karate class.  Many students come in shy, apprehensive
and doubtful that the experience will be for them but they show up wondering,
what can I learn?  Children especially come in wary to a room where there
are dozens of people training with intensity and lots of noise. It is easy
to forget what a new member sees when all you see is your ”normal”.
