A powerful athlete is not a strong athlete, but one who can exert his strength quickly. Since power equals force times speed, if the athlete learns to make faster movements he increases his power, even though the contractile pulling strength of his muscles remains unchanged. Thus, a smaller man who can swing faster may hit as hard or as far as the heavier man who swings slowly.
Bruce LeeLike everyone else, you want to learn the way to win, but never to accept the way to lose - to accept defeat. To learn to die is to be liberated from it. So when tomorrow comes you must free your ambitious mind and learn the art of dying!
Bruce LeeSelf-knowledge is the basis of jeet kune do because it is effective not only for the individual's martial art but also for his life as a human being.
Bruce LeeWhat we are after is the root and not the branches. The root is the real knowledge; the branches are surface knowledge. Real knowledge breeds 'body feel' and personal expression; surface knowledge breeds mechanical conditioning and imposing limitation and squelches creativity.
Bruce LeeForget about winning and losing; forget about pride and pain. Let your opponent graze your skin and you smash into his flesh; let him smash into your flesh and you fracture his bones; let him fracture your bones and you take his life! Do not be concerned with escaping safely- lay your life before him!!
