“Madness habits” can refer to unhealthy patterns of behavior that contribute to stress and anxiety, such as a lack of sleep, excessive caffeine or screen time, poor eating, and overloading one’s schedule. It can also refer to the negative habits that become cyclical, like a “dirty, little, self-repeating circle of ideas,” or the routines that shape our lives, even if we’re not fully aware of them. In other contexts, “madness” can refer to March Madness, the NCAA men’s basketball tournament, and the habits of successful teams, or even to concepts in literature and philosophy, as in The Wall Street Journal’s analysis of team habits.
