In terms of music, can't life be considered a blank sheet of music?
To look at it that way gives way to new outlooks and expressions but in the end everything comes down to one simple thing. With life, new experiences.
To view life as a sheet of music then every experience and every trial and tribulation must be the notes, lines, and other musical properties. Our score of music will continue to fill up as we grow. I wonder how big the musical collection of one person would be if life could be measured by music sheets? (Hm...makes me think of the song Seasons of Love by Rent lol)
