On the other side of the wall, someone was watching a movie on television. I obviously could not see it and could not even make out the dialogue, but I could hear the sound track clearly.
From listening to the music, I could tell when drama was occurring, when things were romantic, when the mood was light and when the end of the movie was nearing. As the music changed, I assume the plot and emotions corresponded to the tone.
Think about the sound track of your life. What songs are playing? And if you don't like the mood that it is creating, what can you do to change the melody? You are in control of making your own music.
