JKD to look at its truth was defined in martial art base to say jkd is all things one must be mistaken Bruce Lee never taught the student to climb the tree was jkd yes jkd is a non classical combat modified gung fu system where the art of selfdefence is the goal to understand thru the tools aquired there they can be carried on to other aspects of the persons life and coping skills but everthing you do is no way jkd just your personal daily life activity and the tools that one learns will only work for that person as well as they can use them I would not learn basketball if I wanted to learn jkd but I may use jkd as a vehicle to help me improve on learning basketball but basketball would still just be basketball and jkd will still be the aproach bruce lee used to express and teach his idea of the martail arts not to be fussed over
