This chapter explains the rules that guide the techniques for behavioural change. In different spheres of life there often occurs a need to change a behavior, for example quitting alcohol, or a tactic in a game such as football. Dungy Tony, a new buccaneer’s couch, implemented a technique for habit change in a bid to reform the team, and make it competitive. He states in section one that it is easier to adopt a new behaviour if something is familiar with the new routine (Duhigg, 2012).The golden rule of habit change, therefore, is keeping the old cues, and rewards but changing the routine (Duhigg, 2012).Wilson, an alcoholic, says in section two that once you recognize the cues, and rewards to your habit you are half-way done reforming them (Duhigg, 2012).Therefore, once you discover cues, and rewards you only need to find different routines that would continue satisfying them in the same ways. In reforming behaviours in Buccaneers’ team, for example, Dungy was successful because he used cues that players were already accustomed to. Apart from applying the golden rule, beliefs also play a role in reforming habits. For example, as stated in section four, a victim of alcohol who applied the rule reverted back to old habits when subjected to stress while those who believed in a spiritual being did not revert back (Duhigg, 2012). It is also important to note that reforming habits requires efforts and dedication. Without efforts put by the victim, the old habit may not simply disappear.
