“By engaging in cognitive reappraisal, and telling ourselves a different story about what is happening, we can subvert the entire willpower paradigm. Some research has shown that willpower is like a muscle, and it gets tired with overuse. But it only gets depleted if there’s a struggle. Games change the struggle to something else. They make the process fun, and as Mischel showed in his research, we are able to persist far longer and without the same level of teeth-gritting willpower depletion.”
