What is Jeet Kune Do?

 Jeet Kune Do can be described as an art of style of no styles. It is a formless hybrid martial art that continue to evolve and improve as Bruce Lee wants it to be.  It is mainly about adopting your own style as it described by Bruce Lee: 

"Don't get set into one form, adapt it and build your own, and let it grow, be like water. Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup; You put water into a bottle it becomes the bottle; You put it in a teapot it becomes the teapot. Water can flow or it can crash.Be water, my friend."
