Bruce Lee-

" Be like water making it's 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. If 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. Now, water can flow or it can crash. Be water, my friend. "
