What really matters-the real "pillar of self defense" is-for the umpteenth time-mindset. Most people are disinclined to use violence against their fellow men, even when confronted with malicious and violent intent. It's not that it's not within their nature-it's simply that they have not ever had a reason to go there, and usually aren't trained to: the will to kill, the inclination perpetrate violence on a human being, is something that doesn't arise from motivation-the violent actions and intent of others-for everyone. Mindset-the will to use violence, and the ability to channel one's emotions into that violence, are of paramount importance: the retraining of the "flinch reflex," the ability to manage adrenalization, these are far more important than grapplling, or striking,or cutting with a knife, or hitting with a stick, or firing a gun.
The primary "pillar" of self-defense training, then, is training that develops the ability to control and channel fear, and the will and ability to act violently, and immediately......the secondary pillar is the one we should depend upon, and that is situational awareness....the tertiary one would fall under strategy, and consists primarily of not only being aware, but avoiding situations (or locales) with violent potential......
