I was inspired to read this book based on the character Whendy Rhoades from the Netflix series Billions. Apparently, her character is loosely based on Dr. Kiev. To me, the book was entry-level cognitive-behavioral-therapy type stuff, self-help, in the context of stock trade. It is good to review the big ideas; (1) How am I feeling? (2) What stimulus triggered this feeling? (3) How am I reacting and how are these reactions predetermined by historical patterns of behavior? In other words, mindfulness. I was hoping to find an original idea or new insight or fresh synthesis - maybe I missed it!?
