There’s only one basic principle of self-defense- you must apply the most effective weapon, as soon as possible, to the most vulnerable target.

Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way round or through it. If nothing within you stays rigid, outward things will disclose themselves.

Jeet Kune Do favors formlessness so that it can assume all forms and since Jeet Kune Do has no style, it can fit in with all styles. As a result, Jeet Kune Do utilizes all ways and is bound by none and, likewise, uses any techniques which serve its end.

Empty your mind, be formless, shapeless - like water.

Where there is no style, there is no slave. Martial Arts mean honestly expressing yourself. No style. No slave.

Boards don't hit back.

Do not allow negative thoughts to enter your mind for they are the weeds that strange confidence.
