The above btw applies to many TMAs so, if you want to study a TMA and not Krav Maga, MMA etc, one of the first things you need to do is speak to the Head of the school, or a senior student, and ask what the main goals are. If, like my school, the first word is "we train fighters so you can go home to, and protect, those you love" you have found a school that should work well. If they say something like this though, "Our mission is to offer a center for mind and body development in pursuit of excellence through personal achievement and constant physical and mental improvement by maintaining the traditional martial arts training regimen," the school is likely not the place for self defense
