Out of the box

Each of our lives are like a story. Each year is a new chapter, a new phase to our life. And each of our stories are connected in one way or another. All stories have a purpose and a set of characters. If this story has all the components present, it shall be completed. Yet, some stories may never be completed. A constant loop, a never ending repetition of events that seems endless. Some may have a missing purpose, others might lack in characters. How can this story be complete?
