When two bricks collide, it’s pure friction. If they hit hard enough, they will shatter. Being strong in the way a brick is strong is a fragile and limited kind of strength. It’s one-dimensional. But when water crashes into a brick, it yields. It can crash with enough power to wipe out a brick house, and still it can flow around it effortlessly. It’s a much more versatile and powerful kind of strength. How you train and develop your body determines if you become like a brick, or like water.
“Water is fluid, soft, and yielding. But water will wear away rock, which is rigid and cannot yield. As a rule, whatever is fluid, soft, and yielding will overcome whatever is rigid and hard."
