Suggest everyone read "With Winning in Mind", by Lenny Bassham. Excellent book on how anyone can excel at any task, especially geared toward shooting since Lenny was a Gold Medal Olympic shooter. After mastering mental training techniques for himself and attaining his shooting goals, Lenny started Mental Management Systems, a business to train others in how to use these techniques in any area of life. Lenny is recognized as a teacher of the world's best in mental preparation for sport and business. His clients include: FBI, Secret Service, Navy Seals, Marshals Service, Army Marksmanship Unit, Marine Corps Marksmanship Unit, and various Olympic teams from around the world. I read his book with some hesitation, but it comes highly recommended by many top shooters in USPSA and other organizations. Never gave much thought to the importance of mental training before, but since applying some key techniques from the book I have quieted the distracting voices in my head and seen my classifier scores progress in an upward direction. I am a believer!
