This book is somewhat of a self help book on ways to be more immersed in the present moment. i.e.- being engaged in conversation or fully grasping you're surroundings. This is important for everyone but especially performers, athletes, speakers, but the ones whom are most largely effected would be 17 and under. This book just glances the surface of the vast topic but sheds light onto some of the foremost thinkers on both sides.
