There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
Bruce LeeA good teacher can never be fixed in a routine... each moment requires a sensitive mind that is constantly changing and constantly adapting. A teacher must never impose this student to fit his favourite pattern; a good teacher functions as a pointer, exposing his student's vulnerability and causing him to explore both internally and finally integrating himself with his being. Martial art should not be passed out indiscriminately.
