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.
