What brain chemical(s) is attributed to the deep satisfaction of achieving an important, meaningful or long-term goal?
My understanding is that the shallow satisfaction of achieving an unimportant or short-term goal, such as
- Getting a handful of likes on social media
- Completing a mission in a video game
- Correctly answering a question in a classroom
is mostly attributed to dopamine.
Do larger-scale successes, such as
- Breaking a world record after $1000$ hours of unsuccessful attempts
- Winning a large chess tournament
- Learning a new skill
correspond to a different chemical or set of chemicals?
