This is a good read, and worth the time. Do ten lessons make you a ninja? Are all martial arts the same?
No dojo is the same as another, and each art is like a person, with its different strengths, weaknesses and appearance. And like people, the different martial arts have as much in common as they don’t. The problem is, most people who have never done a martial art like to draw conclusions about all of them based on facile and incomplete evidence.
