Tracy identifies fear of rejection and fear of failure as the two primary performance killers in sales, and, by extension, in most professional contexts where persuasion is required. Fear of rejection manifests as reluctance to initiate contact, hesitation at key decision points, and a tendency to interpret ambiguous responses as negative. It produces the tentative, apologetic communication style that prospects read as low confidence and respond to accordingly. Fear of failure manifests as procrastination, excessive preparation without action, and setting conservative targets that feel safe rather than motivating ones that feel stretched. Both fears, Tracy argues, are primarily formed by early experience and are maintained by avoidance: every time you avoid the feared situation, you confirm the fear and make it slightly stronger. The only way out is through: deliberately taking the actions that trigger the fear, experiencing the reality that it is survivable, and updating the belief accordingly. He recommends what he calls the law of reversibility: the emotions you would feel if you were confident and successful can be generated by acting as if you were already confident and successful. Act the way you want to feel, and the feeling tends to follow. This is not delusion. It is the practical application of what neuroscience has since confirmed about the bidirectional relationship between body, behaviour, and internal state.
