The book goes on explaining how the habit formation works. The foundation of habit is “cue”, flowed by series of action and then closed with “reward”. The cue act as the trigger to the series of automatic action that had been pre-programmed actions which will resulting on thhe reward. Our brain will anticipate this reward once the cue appeared. So the series of action is triggered automatically from our basil ganglia.
If we know the cue, it is possible to try to reprogram the series of action that flows. However, to ensure that this new formed habit stays, we need to have a great will power. Without the will power the individual are most likely to refer back to the old habit, when the pressure is on.
