I have been teaching Practical Shooting for more than a decade。 Watching thousands of students fire millions of rounds over the years has taught me quite a lot about shooting。 It also taught me how individuals process and obtain an understanding of shooting。 I have seen students repeatedly shoot the same patterns over and over again， and I've realized the same drills highlighted the same mistakes。 Over time， it has become easy for me to spot these patterns。 The difficulty was making the student see and understand what I saw。 However， when the student would experience an understanding， they had a breakthrough in their shooting。Over time， I modified drills and created new ones， to highlight the patterns I was seeing so that students would understand what they were doing wrong and comprehend how to fix it。 This book is the product of that refinement。 It contains a simple set of ideas， techniques， and drills; distilled down to an uncomplicated form。 By developing your understanding of the concepts contained in this book， you can achieve your own breakthrough。
