The true master has no need to boast.
Actions speak louder than words.
One of the best examples of a martial arts master is Dan Inosanto. He is humble, down to earth, kind and possesses legendary skills. Looking at his background, that should come as no surprise. He began training in Okinawa Te and Ju-Jitsu at the young age of ten. He then took up Judo with Duke Yoshimura in 1957 and then Chito-Ryu in 1959.
