You should never try to use physical means to settle a problem with someone on the street. The first thing that you should do is try to resolve any issues or diffuse any problems with words. However, if you do find yourself in a situation where you must defend yourself, it's important that you understand basic street fighting tactics to stay safe and come out on top. If you try to avoid fights, learn how to defend yourself, and use the proper martial arts techniques and tactics to defeat your opponent, you can feel safe and confident if you end up in a confrontation with someone violent.
