I think she's got a pretty solid case in that you've got a lot in your head that can completely change how you see a situation or see a scenario happening. So just knowing that and that's kind of what she's laying out here and she does end up talking through that throughout the book, pointing the whole topic at that concept. I don't know that I have any arguments on it, but I think she does a pretty good job of setting up the foundation for the rest of the book with it.
