Quote from : The Magician's Land Book

And if she liked and trusted the person who asked, she would add that yes, it was kind of a lot to deal with: her outward affect was bright and capable, and that was no illusion, but equally real was the yawning pit of exhaustion inside her. She just felt so tired sometimes. And because of everything her parents asked of her, she was ashamed of being tired. She could not, would not let the pit swallow her up, as much as she sometimes wanted it to.
