The first rule was to get down on the subjects level. Taking a picture of your subject on eye level with them will give you an interesting angle that can often reveal more emotion than a regular shot. In order to do this, you have to be willing to get down on the floor, lay down, climb, or whatever else it takes to get a strait on view with your camera. This can be easy or hard, depending on your energy level and what you are shooting.
The second rule is to get a plain background. This rule especially applies when taking a picture of something in front of a busy background that may alter the focus of the picture. For instance, if you are trying to get a shot of a little girl and there is a telephone poll behind her that looks like it's sticking out of her head, the picture won't have the same effect than if the background is just sky. This rule is a bit harder to follow, because it makes you get a little more creative with where you take your pictures to avoid busy background.
