Hello everyone!
I am glad I stumbled upon this thread! I have been thinking about myself since I started my training and even my oldest friends said there is something different about me. In high school I was fairly quiet to people I didnt know personally and was even in my own opinion, really angry for some reason. Although I had maintained fairly good grades and was loved by most if not all but one of my teachers. I was easily frustrated, impatient, and had an almost violent temper. After a few years I noticed that I didnt mind waiting in lines, and my road rage subsided a little {still pops up once and a while :p } I started to read taoist texts and philisophical pieces.
I am sure that back in high school I wouldve loved the chance to fight someone and now that I have the training and am strengthened, I have no urge to fight anyone and avoid situations all together. It was a subconscious change, probably from being quickly humbled by senior students who have been training for 30+ years... I started thinking about what the arts are supposed to be, for exercise, defense, discipline, and to understand ourselves physically, anatomically, and even spiritually.
I am much more contemplative about what I say, how it is said, and when I speak. There are concepts of the arts that demonstrate the quote from Lincoln, "Better to remain silent and be thought a fool than to open your mouth and remove all doubt."
I am more likely to help someone who needs it than I had been. I was very selfish and now believe it is better to be without than to have a constant feeling of desire.
It took time for me to notice these changes in my behavior, but like I mentioned before, my friends even told me that I was different; happier, nicer, more active than I had been. I wanted those changes when I started and I believe that my wanting to change was a big part of it, so as usual, you get what you put in and keep your focus.
I dont think that answered your question but it is my change that I attribute 90% of to my training in traditional kung fu. I hope you find an answer that satasfies you!
