“In contrast to dopamine-fueled feelings of pleasure, feelings of happiness are caused by another neurotransmitter – serotonin. Serotonin also helps create feelings of contentedness, significance, and importance. Among other functions, serotonin is a mood stabilizer. Sure, dopamine will give you the quick pleasure rush, but serotonin will keep you happy in the long term – a positive upbeat mood that chases the blues away.”
