Shoot from different angles and positions. Sometimes it is better for you to move than to ask your subject to move.
Often people stand in front of their subject and only photograph from that position. Explore your subject from different heights and locations. If photographing a child you might miss a lot if you don’t shoot from a lower angle. Get down on the same level as the child. If shooting a group of people stand on a stool or ladder so that you see everyone including the people in the back rows. You can make a person look taller or shorter from the hieght that you are shooting.
If you shoot from different angles and compose your images from different locations you will find your pictures to be more interesting.
