The Moral Licensing of Willpower

The author explains that there's really two different selves who are at constant odds. She says we take one step forward and then feel like, okay, we can now take two steps back. And this concept, she called it goal liberation, I believe,. It's basically we've been working on this one thing, and so that progress that we made can actually cause us to abandon our goal by granting permission for the other self to have their way. The book also talks about how fatigue shouldn't be considered a physical event, but she refers to it as an emotion or a sensation.
