I agree and disagree, there exists a lot of crap in a lot of the traditional martial arts, however I also feel that there's also a lot of good that can be taken from them. About 14 years ago I went from a traditional back ground of Karate and Tae Kwon Do into BJJ and MMA, competed in both as well as K1 rules kickboxing at Pro, this was before most had heard the term MMA and a mention of it returned blank looks.
I was training 5/6 days a week as well as cornering almost every weekend; this was on top of a physically demanding job and it got to an unsustainable level, I started picking up injuries left, right and centre and I admittedly lost my once limitless motivation.
Then my wife gave birth to our child (which is by far the best decision that I/we ever took), I received a promotion that took me away from a lot of the physicality but that also extended my working ours; I gracefully bowed out of most things martial arts but continued to hit the bag and train at home, becoming more interested in building up my strength and size.
Then whilst travelling away with work some months ago, I got talking to an old colleague that I hadn't seen for years, doing the usual catch up and I found the first flicker of a flame inside me that has rekindled that love I once held for martial arts.
I made the decision to not jump back into MMA and BJJ as I am honestly worried about re-occurring injuries and I don't have the time to dedicate. So I found Wing Chun, and yes whilst there are gaps in the system when compared to MMA, (there are also gaps in BJJ, Muay Thai, Boxing etc when compared to MMA, everything is relative...)
I'm studying it for itself and to see what it can bring to the table; so far I'm impressed and most of all I'm ENJOYING it.
