People are like endless puzzle pictures. We tend to have missing pieces. Some realize what they are sooner, while others take longer to understand that they're missing a piece. You see we all have puzzle pieces around our edges. For some people it's easier to look for the piece they're missing since it's at the center of the picture. Others, however, don't know what to look for since it's at the edge. You need to see the bigger picture first to find out what the edge look like. Otherwise you wouldn't even know what to look for.
