a pervious teacher of mine ( Zen & Aikido) would talk about ...."IN daily life " and that was the actuall catch phrase he would use. in my memory ( he has since past away) he would use these words at least once in every class.
those were good memories and very wise words.
as for myself ,and i am sure with lots of others, we have had martial arts in our lives for so long it is imposible to see the impact of those arts because it is imposible to know where and who we would be with out it. i remember Buzz Durkin saying "every time you do a kata, you redifine who you are".
i also remember a quote from a japanese Koryu teacher saying "i practise martial arts because it teaches us to be human". i feel most people might start martial arts for selfdefense reasons or fitness but continue because it forfills our basic need for self-improvment.
