“As children, we are driven by our inner desires to learn, to discover, and to help others. But as we grow, we are programmed by our society to need extrinsic motivations: if we take out the trash, study hard, and work tirelessly, we will be rewarded with friendly praise, high grades, and good paychecks. Slowly, we lose more and more of our intrinsic motivation. Extrinsic promises destroy intrinsic motivation.”
