I was especially impressed by the section on developing your senses, as this is not the first time I've read this type of information. Several other books I've read mention the necessity, and advantage, of developing your senses. I am personally taking this to heart. After all, having better developed senses should benefit in all areas of life.

Mention has been made of the simplicity of this book. In defense of the author, the majority of people write on a third-grade level and read on a level not much higher. In an effort to reach the majority of readers, an author shouldn't write on a level challenging to college students. "Write simple, write for the masses."

I was also impressed with the author's inclusion of criminal organizations. Many authors would find including criminals as a "good example" to be distasteful. However, criminal organizations often use methods to achieve their goals which are wholly applicable to the topic of the book. As the author states, "If a tactic, technique, or training method works, use it, no matter what its origins. In other words, whatever gets you through the night."
