Thank you for that opening quote, Xfile. I believe that state of effortless mindfulness, the zen, the 'zone' whatever is a crucial requirement in our game. Unless you have a 'bot' doing all the work for you, there are so many details, mental and emotional distractions pecking constantly at our attention that, in the heat of battle, it's a wonder we can remember and bring to bear what we know about handicapping and wagering at all, let along effectively and profitably.
After mastering one's handicapping software or method, and devising wagering strategies suitable to one's temperament and edge, '
mental skills' are what puts it all together.
Brushing up on Anthony's website info and reading a few particular lines from the opening quote, it appears he has embraced, or perhaps preceded by decades, the recent 'Secret' craze and continues to espouse the timeless aspects and utility of self-knowledge.
Time to check up on that a bit further, and re-read my old copy of
Betting on Yourself
