The book is specifically called "A Ninja of life" and not "A Ninja in life". The idea being that "of" emphasizes all aspects of the person's life, as opposed to one area in his life. At the end of each story, there is a section which contains reflective material: 1. Lesson/s learned; 2. Fun fact; 3. Food for thought; and 4. What did you learn? The reader is given the opportunity to respond to "Food for thought" and "What did you learn?"
