SHOW SUMMARY

In this episode of Selling from the Heart, Larry Levine and Darrell Amy welcome mental performance coach Collin Henderson to explore the psychology behind sales performance and why mastering your inner game is essential to sustainable success.

Collin begins with a simple philosophy: “Never sell, serve.” He challenges sales professionals to move from an “I-centered” mindset to a “we-centered” approach focused on curiosity, value, and helping customers succeed.

The conversation explores how limiting beliefs, self-image, confidence, resilience, and self-talk influence performance long before sales techniques are put into action. Collin also introduces The Oz Method, connecting the brain to belief and curiosity, the heart to emotional connection, the lion to courage and vulnerability, and the yellow brick road to the habits and systems that make success repeatable.

Ultimately, Collin challenges sales professionals to examine the stories they repeatedly tell themselves. Your strategy matters. Your skills matter. Your market matters. But your biggest competition may still be you.

Combine belief and curiosity, emotional connection, courage and vulnerability, and disciplined processes. Tra
