In life we struggle to overcome emotions , the job of the actor is to be swimming in them. It's all work in progress. Life is work in progress. Life is accidental, not rehearsed. Life is a continuous thing, so don't do a scene piece by piece.
Life is crazy.
Life is full of interruptions. In the middle of tragedy have an interruption. Life is not a high noon shot out. Life is not up front. Life is off the wall, can't be predictable.
