I began to start reading this book during my 11th grade year in High School. My goal back than was to understand people gestures and thoughts. Plus learn how to avoid being read sine my facial expressions are so easy to read. Those days were so painful, lost a huge amount of money. This was very useful during high school it even help me to land my first job. Now it was not at all easy to just read the book and put it in affect. It actually took sometime and since I get easily distracted, this book also helped me to concentrate.
