Andrew feels good about himself. He doesn't know exactly why he is so happy, but every day he looks forward to his schoolwork and chores. "I play a game," he says. "I make a list of everything I have to get done, and then I try to finish it all before a certain time. For some reason, I feel great when I beat my time." Based on this information, why is Andrew happy?

Respuesta :

It appears that Andrew gets a nice rush of endorphins and dopamine when he successfully completes a task. When you make goals, and complete them competitively - you can get a feeling of success! =)
