When I first starting learning wing chun from my step brother I didn't have any hands or in fighting experience really, mostly kicking. So wing chun just happened to the be the first style (aside from Muay thai/western boxing) that took the infight to a higher level.
My reflexes and general hand speed increased with wing chun, I liked the simplicity and that everything you needed to fight with was learned in the beginning, and that development was soley based on the individual, and the fact that there was only three forms, (because quite frankly I've never thought forms did anything for fighting...just ask the shaolin folks who practice 900 forms but still couldnt fight a 3 year old effectively)
Umm....to this day, I feel as if my wing chun was the best thing to round out my fighting, although most recently I'm also thinking outside the box as well as not one style has all the answers.
Another thing I liked is that wing chun's maxims and fighting philosophy can translate to many fighting styles. I think of wing chun now moreso as an everchanging energy, and the study of it helps us learn how to deal with, and use energy. I don't take things so literally now with the system. It changes based on my current needs.
"I don't know if anyone is known with the art of "sitting on your couch" here, but in my eyes it is also to be a martial art.
It is the art of avoiding dangerous situations. It helps you to avoid a dangerous situation by not actually being there. So lets say there is a dangerous situation going on somewhere other than your couch. You are safely seated on your couch so you have in a nutshell "difused" the situation."
