I would be lying if I said that trying to bring him down didn’t take over my entire life. See, having a nemesis is like drinking a vat of coffee on a day you’ve had no sleep—you feel shaky and tingly all over, like you can conquer the world, but you also want to cry, and time passes by in a blur while you behave without any sense of reality or consequence. And sometimes it makes you feel more alive than anything ever has.
