question:
Review: I have only read the first 44 pages of this book, so I'd need to read the rest. So far, though, it is interesting but seems fuzzy. The writer makes a lot of claims but I was rarely sure if they were proven or just speculation. This is the kind of sentence that makes me queasy:"Given all the activations happening at once [in the brain], physical performance probably uses 100 precent of the brain" (p. 39).Probably? Why? Does any one activity use 100 percent of the brain? And if physical performance does, why is that important? 
 Polarity: Negative
answer:
True


question:
Review: I found this plot to be to contrived in that many of the scenes were just to clearly made up for me to become vicariously involved. The twists and turns in the plot were simply to convenient for me to appreciate a sense of natural flow that good novels must have. For example: The scene in which Gault (the killer) has been seen using the same restaurant that the main character spontaneously finds herself in. Imagine, in New York no less! Not only that, but the killer is using the main characters visa in the same restaurant. And then the genius software engineer niece who just happens to be working on a huge computer program in the law enforcement field. I'm sorry, but this tale is just to unbelievable. It might make a passable B grade film, but I wouldn't want to see it. 
 Polarity: Negative
answer:
True


question:
Review: I got nothing out of this book. I've read many self-help books, and this is among the worst. McWilliams provided worn-out cliches, and the book reads slowly. If you want good selp-help books, check out Denis Waitley and Anthony Robbins. 
 Polarity: Positive
answer:

False
