Although it is important to be able to defend yourself physically when violently attacked, it is even more important to prepare yourself mentally before you reach this point. This mental preparation falls into five categories, the five "A's."
Awareness: Be aware of everything around you, everything that could and may happen to you. Denial of danger is the biggest mistake of all.
Attitude: This involves the way you carry yourself, how you speak and act. Be friendly, but suspicious. If attacked, be angry, but control the anger. Do not be intimidated; be assertive. Your attitude will go a long way in preventing a potential attacker from even contemplating an attack on you.
Avoidance: Take steps to make your environment as safe as possible by avoiding potential problems. The more avoidance procedures you adopt the less your chance of being attacked.
Assessment: Make a threat assessment of each threat potential and decide what action may be required. Choosing what to say and do in a given situation is very important since you may make the situation worse by your words or actions.
Action: Once the above categories fail, you will have to fight for your life. Overcome any fears you may have and act with speed, power, and efficiency. Do not hesitate to act.
