While it may come as a profound surprise to those of us who are in the throes of an emotional or life crisis, the fact remains that the answer to virtually all of our problems resides within us already. It exist in the form of a vast reservoir of free-flowing energy that, when channeled to our muscles, can give us great strength and, when channeled to our brain, can give us great insight and understanding.
Bruce LeeA 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.
