"A fixed habit is supported by old, well-worn pathways in the brain. When you make conscious choices to change a habit, you create new pathways. At the same time, you strengthen the decision-making function of the cerebral cortex while diminishing the grip of the lower, instinctual brain. So without judging your habit, whether it feels like a good one or a bad one, take time to break the routine, automatic response that habit imposes."
