The moment a person's cue appears, they begin to anticipate or crave their reward even before doing their routine and actually receiving the reward. Duhigg says “This explains why habits are so powerful: They create neurological cravings” (47). People would not be satisfied and often irritated when they would crave their reward but not receive it. Duhigg talks about an experiment in his book about what a man named Wolfram Schultz did with a monkey named Julio. Schultz would strap Julio onto a chair in front of a computer. Julio would have to touch a lever every time he saw a shape and he would be rewarded with blackberry juice. Once Julio knew what to do he started to get into the habit of pressing the lever every time he saw a shape. Schultz would see a spike in Julio’s brain once he received the blackberry juice. After the habit was deeply embedded in Julio’s brain, Schultz noticed that the spike would occur the second Julio saw the shape on the computer screen. Schultz then changed the experiment to wait a few seconds for the juice to come out and Julio would get mad and depressed about not getting the juice. Schultz realized this was a craving. Duhigg says “...craving, it turns out, is what makes cues and rewards work. That craving is what powers the habit loops”(19).

After a long process, I now believe that I can change my habit of cracking my neck. I believe that I need to do this for myself and not because someone told me to stop. Duhigg says “Belief was the ingredient that made a reworked habit loop into a permanent behavior”
