Learn not to fear pain, which is the reason why so many people choose not to defend themselves. Effective self-defense techniques teach you to either ignore the pain, or to use it to motivate yourself against an opponent. Remember, you probably will experience pain as a result of a blow from your opponent, and when you deliver a blow as well, so you must learn to accept it.
Learn the vulnerable points on your opponent's body when you teach yourself self-defense. On both women and men, these include the knees, the abdomen and the eyes, and with men, you can also add the groin area. A punch or a kick to any of these areas, if delivered with enough force, may render your attacker helpless.
Use your leg first when you are trying to deliver a blow, since it is longer and more powerful than your arm. Develop both your kicks and punches equally when teaching yourself self-defense.
Read instructional books on common self-defense techniques in order to practice the right defensive moves. The right book should contain detailed photographs on how to deliver a blow accurately, and how to practice your blocks, punches and kicks equally.
Watch instructional videos to teach yourself the proper defense techniques. Videos offer a distinct advantage over books, since they can show specific types of movement in a fluid manner.
Remain constantly aware of your surroundings, which may be the best overall way to teach yourself self-defense. Aggressors are less likely to attack you if you notice them first, and seem prepared to deal with their advances. Remember, your opponent is using the element of surprise to succeed, so your best defense is to be alert.
