At the core of Bruce Lee's martial arts, acting and philosophy, is his now famous quote:

"Empty your mind. Be formless, shapeless, like water. You put water into a cup, it becomes the cup. You put water into a bottle, it becomes the bottle. You put it into a teapot, it becomes the teapot. Now water can flow or it can crash. Be water, my friend."

Bruce believed in the honest expression of each unique human being. To honestly express oneself, Bruce believed that one must be like water: adaptable, flowing, always changing and growing and never becoming fixed in one style or one way.
