I liken the process for my anger management clients to steering a car, you make thousands of small adjustments to the position of the vehicle on the road, and are paying attention to hundreds of variables at a given moment, traffic in front, behind, traffic lights, children, the policeman six blocks ahead, ect. As you do this, you keep the vehicle going in the direction you want, at the speed you want, in a safe way for yourself and other drivers. You avoid potholes.
