ON ACTING: Impulsivity
The old adage reads: "Fools rush in where angels fear to tread." Amendment: "Fools and exciting actors rush in where angels and dull people fear to tread."
That does not mean, however, that that good acting is only a fast-paced activity. It can be slow; with deep elongated pauses between lines and actions. But...the energy within those pauses--during any and all reality induced cessations of activity--is highly inner-activating; there is a lot of vibrant, fast-twitching inside the actor/character's body and mind, the spinning of his or her wheels, racing internally, to choose, to decide, to act...impulsively.
