This is marketed as a guide to mental strength for athletes, business-people & others; but my high hopes for the book are somewhat diminished by its presentation, which comes across amateurish, low-budget & unprofessional. A little bit cheesy. The training philosophy seems overcomplicated, w/strange paradigms (ie; "Pillars" "Instruments" "Concentrations") & terms ("Friendly Eyes" "Consumerism" "Story Thinking" "Zooming"), which often seem obscure & inaccessible. The vocabulary isn't particularly intuitive & it's not the terminology that I would use. Eccentric at times. Although there are some interesting references to professional athletes & their habits, the book at times seems prone to excessive name-dropping (ie; Zidane, Materazzi, Federer, van Basten, McEnroe, Borg, Navratilova, the Williams sisters, etc.), which is offputting & confusing, esp for readers who aren't avid pro-sports followers. Love the cover art & concept. She generously provides a structured assignment rubric at the end of the book, w/weekly worksheets. There are some useful takeaways here ("Visualization" "Curiosity" "Good Mistakes" "Rituals" "Trigger Words" "Flow") & I appreciate the references to Breathing (& Andrew Weil), as well as the proposition that the mental game is equally as important as the physical game; but these many assets are obscured by the odd presentation of the book. Instead of this guide, I'd recommend Timothy Gallway's "Inner Game of Tennis" (& other volumes in the Inner Game series), for their simplicity & direct, intuitive, effective presentation of methods.
