THough I also have to thank my parents for a good upbrining, I also could never repay my instructor. In fact I'd like to think that my instructor had a lot to do with who I am today. When I was younger and began my training a lot of my friends would just hang around somewhere, Kenpo was really the first thing I had to work hard at in order to achieve a bb. Sure I could have hung out at the local mall with my friends, but I would definately not be who I am today. You go in everyday you work hard, you sweat, and sometimes the bb seemed impossible, but it was attainable, if I can do it, any of you can. A lot of the time you spend in practicing in your studio, dojo, dojang, ect is also time that you spend growing hopefully into a positive light for society, and most of this is due to a good instructor. Though, I do consider myself one of the lucky ones, for many reasons, I never really lacked anything in life, today as I am much older, I often wonder how many kids that are involved in martial arts, are being brought up solely on their instructor's teachings. That is that the instructor with that 1hr 1.5hrs ect has more influence on them than their own parents. Its funny really when you think about it, I know a lot of people who disagree with me on that, but there are kids out there that are completely neglected by their parents, albeit due to jobs, or sadly in some cases due to utter stupidity like watching a sitcom on TV, and the only positive teachings and experiences are taught at their place of practice.
