People are often at their best when working toward a long-term, meaningful goal that they believe is achievable, like earning a degree or getting a promotion. That’s because not only is dopamine released when you finally achieve a long-term goal but it’s also released with each step you make as you move closer to achieving it. Having a goal also allows the prefrontal cortex to more effectively organize your actions. And most importantly, achieving the goal is often less important to happiness than setting the goal in the first place.
