In every story worth telling the hero undergoes a transformation. To experience this transformation he must face adversity, he must struggle through pain, and he must persevere through suffering. It’s during what’s called the Second Act, the longest part of the story, that he struggles most. Your grandpa, PaPa, is in a Second Act season of life.
In the Second Act the hero is refined through the fires of struggle and suffering. As the hero is being refined, his goal is reshaped – not abandoned – because his struggles have helped put things in perspective. It’s the shift in perspective that causes the hero to be transformed into who he must become in order to get to the end of the story.
