I refer to my hands, feet and body as the tools of the trade. The hands and feet must be sharpened and improved daily to be efficient. It is true that the mental aspect of kung-fu is the desired end; however, to achieve this end, technical skill must come first. The techniques, though they play an important role in the early stage, should not be too restrictive, complex or mechanical. If we cling to them, we will become bound by their limitation. Remember, you are expressing the technique, and not doing Technique number two, Stance three, Section four? Practice all movements slow and fast, soft and hard; the effectiveness of Jeet Kune-Do depends on split-second timing and reflexive action, which can be achieved only through repetitious practice. When performing the movements, always use your imagination. Picture your adversary attacking, and use Jeet Kune-Do techniques in response to this imagined attack. As these techniques become more innate, new meaning will begin to emerge and better techniques can be formulated. - Bruce Lee
