Thank goodness so many veterans got addicted to heroin. If they hadn’t, we’d never understand how New Year’s resolutions actually work.
If you’re staring at a screen with an confused expression, you may want to check out this NPR story. To quote:
In May of 1971 two congressmen, Robert Steele from Connecticut and Morgan Murphy of Illinois, went to Vietnam for an official visit and returned with some extremely disturbing news: 15 percent of U.S. servicemen in Vietnam, they said, were actively addicted to heroin.
The idea that so many servicemen were addicted to heroin horrified the public.

This is a tremendously awful failure. The government responded with a comprehensive treatment program, which in part tracked addicts during and after their term of service. What they discovered was even more shocking:
95 percent of the people who were addicted in Vietnam did not become re-addicted when they returned to the United States.
This flew in the face of everything everyone knew both about heroin and drug addiction generally. When addicts were treated in the U.S. and returned to their homes, relapse rates hovered around 90 percent. It didn’t make sense.
So what happened? Researchers now believe that the servicemen had a physical addiction which was tied to their environment. They became used to life in the jungle and associated all of the routines in the theater of war with their drug usage. When they got home, the environment was no longer familiar. Therefore, it was easier to quit.
What does this say about New Year’s Resolutions? You’re probably going to fail at them, unless you radically change your environment. If you really want to give something up, try changing other, seemingly unrelated routines as well. You may have a physical addiction to the environment.
Failure is the secret to success. As awful as drug addiction is, this analysis is of landmark importance in understanding motivation
