《Be Water , My Friend 似水無形，李小龍的人生哲學》1
- 「Be Water，My Friend !」，意思是武者不被形式所拘，要像水一樣流動，既柔軟又剛強堅韌；既能適應萬物，又能匯聚為強大的力量。
- 當水被某種障礙物擋住時，它會平靜等待，卻又伺機而動；一旦移開障礙物，就會立刻奔流過去，毫不遲疑。 所以，李小龍說，面對競爭與阻礙，「水，永遠都是放鬆卻做好準備的。」
- _[“I said 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 into a teapot, it becomes the teapot. Now, water can flow, or it can crash. Be water, my friend.”
「人無常勢，水無常形。」
