Answer:
In this diagram, the circle represents the circle of concern - the things that we worry about or are concerned with. The center circle in the middle represents the circle of influence - the things that we have control over or can do something about. The outer circle represents the circle of neglect - the things that we don't have influence over or can't do anything about. The diagram suggests that we should focus our energy and attention on the things within our circle of influence, rather than worrying about things in the circle of concern or neglect.
