In this day and age where it seems like everyone and their mother owns a gun, what are some of the applications and uses of Wing Chun? What purpose could it possibly serve? Well, let me tell you: martial arts aren't JUST about self-defense. There is much more to it than that. If there wasn't, then everyone would have stopped going to class as soon as the first automatic weapon came off the production line.
You will get out of Wing Chun what you put into it. Therefore, if you do not train, if you do not practice your forms, if you do not put yourself through a constant process of doing, analyzing, and reevaluating, then you will get very little.
This holds true of all aspects of Wing Chun, but it is especially true during forms training. When you pay attention to your techniques, making sure you are doing them correctly, figuring out what you could do to be better, Wing Chun can take you into another world. Nothing else exists or matters.
If that's what you want, that's fine. Maybe you started attending classes just because you did not feel like sitting home and watching SURVIVOR every night. However, if you want to master the art, then you need to get up off the couch and practice.
