Brett Steenbarger, a clinical associate professor of psychiatry and behavioral sciences at SUNY Upstate Medical University, is one of the world’s most highly sought-after trading psychologists. Here, he breaks down the three pillars of trading psychology—emotional, cognitive, and spiritual development—and shares the recipe for trading success. Explaining that deliberate practice, adaptability, creativity, and best practices are all characteristic of the successful investor, Steenbarger provides practical advice on how to implement these attributes to one’s approach, and he discusses how to deal with performance anxiety, frustration, and negative patterns of thinking that can hinder traders from operating at their best and from caring for their psychological wellbeing.
