One of the more difficult aspects of ourselves to identify and accept is whether we are operating from a scarcity or abundance mindset.  If you are not familiar with these concepts, the terms originated with Stephen Covey in his book The 7 Habits of Highly Effective People.  The scarcity mentality person sees the world as having finite resources.  Imagine a pie.  If one person takes a bigger piece of the pie, then the others inherently get smaller pieces.  The scarcity mindset person predicts the worst and expects to be disappointed.  The abundance mentality person has a deep inner sense of personal worth or security.  They believe that there is plenty out there for everyone with some left over.  They are optimistic and hopeful for the future.
