The Power of Habit includes scientific findings on habit formation and change from the fields of social psychology, clinical psychology, and neuroscience. This is not a self-help book conveying one author's homespun remedies; it's a serious look at the science of habit formation and change. Power of Habit is more journalistic, though it does have the appendix at the back that talks about how to implement habit changes. The Golden Rule is that “bad” habits are very difficult to eradicate. Instead, seek to change them/ reprogramme them/ overwrite them with a new routine. Cue stays the same, reward stays the same, craving stays the same, but the routine linking the cue to the reward is changed.
