How Long Does It Take To Master Jujitsu?
well it is good for you to master at least one martial art and you have hinted at Tae Kwon Do. I know that for many martial arts it can be a lifetime achievement if you want to reach grandmaster or something as high as grandmaster. It is always good to study other martial arts to know more about your opponent but I would suggest sticking with one martial art and that for you, would probably be Tae Kwon Do.
