How to Shift From Outcome to Mastery Mindset

In this episode, Jeff Greenwald—world champion tennis player, licensed therapist, and sports psychology consultant—offers a rare glimpse into the intersection of clinical therapy and high-performance coaching. Jeff highlights how anxiety has become the predominant struggle both inside and outside of sport, often crippling athletes and families alike. Drawing on nearly three decades of experience, he explains how his dual training allows him to work not only on performance enhancement but also on the deeper roots of anxiety, perfectionism, and family dynamics that shape an athlete’s experience. He shares how he integrates Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), Motivational Interviewing, and Somatic Psychotherapy, tailoring each to the unique needs of athletes. Jeff clarifies how sports psychology typically focuses on attention control, motivation, and performance skills, while clinical practice digs into family systems, emotional regulation, and underlying anxiety. Listeners will also hear about Jeff’s practical frameworks, including the four dimensions of focus (narrow/broad, internal/external) and his “remote control” metaphor from The Mental Edge for Young Athletes. These models help young athletes understand they have multiple tools at their disposal—but it’s their responsibility to choose and apply them in the heat of competition. A major theme of the conversation is Jeff’s emphasis on the “permission to miss.” With statistics showing that 70% of kids quit sports by age 16, Jeff underscores the importance of helping athletes reframe mistakes, embrace imperfection, and cultivate a mastery mindset focused on growth and process rather than outcome. Over time, athletes learn to anchor their confidence in the skills they can control—their routines, effort, and perspective—rather than in outcomes they can’t. This framework not only reduces anxiety but also fosters resilience, freedom, and joy in sport. He also shares how parents can best support their children—not by rushing in to fix, but by validating their experiences and normalizing their anxiety. As a competitive athlete himself, and still competing internationally, Jeff has demonstrated how you can transform from a tentative, perfectionistic mindset to a full realization of your ability through the mastery mindset, which also catapulted him to world No. 1 in his age group. He shares how this breakthrough was instrumental to his work and how grateful he is to be in a position to help the thousands of athletes he has worked with over the past 27 years.
