Follow some psychology courses and then review your assertion that it doesn't seem like science.
From a behavioral and cognitive view of psychology, gaining motivation from passages in the book is comparable to observed learning. If the motivation one gains from reading the book results in positive results then according to contingency conditioning theory it should result in reinforcement of the behavior, thereby producing an upward spiral. The book probably also influences humans' by altering their beliefs and therefore perceptions during top-down processing of information.
From a biomedical view of psychology, reading a passage 1000 times probably alters your brain structure in significant enough ways that it alters your motivational attitudes. I think that if you put people who read the book in an fMRI scanner you'll see some difference compared to control people.
