Whether it is photography or parenting, focus concerns the dominant things within our focal point. In essence, whatever parents devote their attention to, becomes the emphasis within the home. Just like in the case of the photographer, whatever the camera was focused on, appears as your picture.
Children are quick to learn what their parents' real focus within the family structure.
Unfortunately, some parents fool themselves by thinking they are focused on 'respectable' areas, when the 'real' focus was on self-gratification or some other undesirable quality. A challenging question is to identify what is the actual focus of child training. Children learn if the focus is good physical attributes, to have a good time, maintain a clean room, maintain secrets, practicing good character qualities, or to worry about what the neighbors think. I often attempt having parents remember that children are in our direct care for a few years and the main object is preparing them for the adult world. This helps put some of the background of daily challenges in context.
