«“Dr. Hacker is one of the leading authorities on performance excellence. This book includes some of the same techniques and strategies she has been implementing in her own work with professional, elite, and international competitors for the last two decades. Her approach with our team wasn’t simply ‘plug and play’ coaching. It was individualized and personalized. That showed me that she respected each of us as individuals and was committed to making us the best that we could be. Whether you are a corporate executive, youth athlete, teacher, coach, artist, parent, or elite athlete, the knowledge and opportunities for application in this book will assist your training and performance.”

“In cutthroat, competitive arenas, the focus is often (mis)placed on your opponent or the other team. In Achieving Excellence: Mastering Mindset for Peak Performance in Sport and Life, Dr. Hacker helps center you, the performer, by highlighting the mental skills and strategies that will help close your performance gap in sport and life. By focusing on your own game through self-awareness and personal control, you are much more likely to enjoy the journey in your own pursuit of excellence.”
