"KEYS"

So, I went to a Karate seminar today at my old dojo.  (EXCELLENT, IMPORTANT lessons.)  The MAIN instructor--VERY INTUITIVELY--said, "There are three aspects of martial arts:  1) how you LEARN it  2) how you TEACH it  3) how you DO/"PERFORM" it   As a "former" (PRE-accident) long-time "student"--and later TEACHER", I concur with his analysis.
