Many of us are white keys, the musical notes that are most common and what we hear the most on the keyboard. Some of us are black keys, those musical notes that are less common and give contrast to the expected melodies of life.
White keys without black keys are boring; black keys without white keys are too intense and unstructured.
White keys need black keys to complete a harmonious sound, and vice versa.
Together, we are the spirit of life–music.
