"Then there's the routine, which is the behavior itself," Duhigg tells Fresh Air's Terry Gross. First, there's a cue, or trigger, that tells your brain to go into automatic mode and let a behavior unfold. It turns out that every habit starts with a psychological pattern called a "habit loop," which is a three-part process. His new book The Power of Habit explores the science behind why we do what we do - and how companies are now working to use our habit formations to sell and market products to us. Parallel parking, gambling, exercising, brushing your teeth and every other habit-forming activity all follow the same behavioral and neurological patterns, says New York Times business writer Charles Duhigg. But after you grew comfortable with parallel parking, it became much easier - almost habitual, you could say. At first, parallel parking was difficult and you had to devote a lot of mental energy to it. Think about something it took you a really long time to learn, like how to parallel park. Understanding and interrupting that loop is key to breaking a habit, says journalist Charles Duhigg. Routines are made up of a three-part "habit loop": a cue, a behavior and a reward.
