“Each happy chemical triggers a different good feeling. Dopamine produces the joy of finding what you seek– the “Eureka! I got it!” feeling. Endorphin produces the oblivion that masks pain– often called “euphoria.” Oxytocin produces the feeling of being safe with others– now called “bonding.” And serotonin produces the feeling of being respected by others–“pride.”
