Because a story is a metaphor for life, we expect it to feel like life, to have the rhythm of life. This rhythm beats between two contradictory desires: On one hand, we desire serenity, harmony, peace, and relaxation, but too much of this day after day and we become bored to the point of ennui and need therapy. As a result, we also desire challenge, tension, danger, even fear. But too much of this day after day and again we end up in the rubber room. So the rhythm of life swings between these poles.
