" Fortunately, suppressing an impulse doesn’t always have to decrease your dopamine—it can actually feel good. The key is the prefrontal cortex, which is responsible for pursuing long-term goals and has the ability to modulate dopamine release in the nucleus accumbens. So suppressing an impulse can be rewarding, as long as it’s in service of your larger values. "
