Replacement is powerful because it works, and where bad habits are concerned it’s the only thing that works. I’ve known people who quit smoking without intending to. They took up running, or some form of regular aerobic exercise, and soon the breathing and relaxation they were getting from the exercise made the smoking feel bad to their bodies. They quit smoking because they had introduced a replacement. People who diet have the same experience. It isn’t staying away from fattening food that works—it’s introducing a regular diet of delicious, healthy food that works. It’s replacement.
