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

Empty your mind, be formless, shapeless — like water. Now you put water into 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.

Bruce Lee, based on the Pierre Berton Interview 1971.
