Here is the finding that changes how you think about breaking bad habits: you cannot eliminate them. The neural pathways that carry a habit never fully disappear once they are formed. If the cue and reward remain, the urge will return. What you can do is replace the routine. This is what Duhigg calls the Golden Rule of Habit Change: keep the cue and reward exactly the same, and insert a new routine in the middle. Alcoholics Anonymous works because it follows this rule. Many people drink in response to social anxiety (cue) and because it brings a sense of relief and community (reward). AA provides meetings that happen in social settings (same cue) and deliver belonging and relief through shared stories (same reward). But the routine in the middle is different. To use this yourself: first identify the cue and the reward your current habit is running on. What triggers it? What does your brain actually get from it? Once you know those two things, you can design a new routine that delivers the same reward from the same cue.
