"Repetition, broadly construed, is in everything. It’s in our breath, and our pulse. It’s sunrise, sunset. It’s spring summer fall winter. The tides, cell division. Bad habits, and good ones. The daily grind. Annoyingly repetitive thoughts. It’s in music, art, dance, architecture. Religion, history. Doodling, nail-biting, toe-tapping, smoking. Menstruation, masturbation, sex. Rhythm is repetition. Rhyme is repetition."
