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 LeeI am happy because I am growing daily and I am honestly not knowing where the limit lies. To be certain, every day there can be a revelation or a new discovery. I treasure the memory of the past misfortunes. It has added more to my bank of fortitude.
