Speed

Many people are very focused on the speed of their movements but that is like thinking that shooting is the only thing a sniper needs to excel at or a mother just needs to give birth. Speed is your perception of the movement and not a finite thing. The more you relax and become aware you will know the movement is coming before it even starts and all will seem simple. The more you tense up the slower you work (note this is not move, I mean work) and it matters who hits first not who strikes first.
