Dr. Andreas Stamatis is a Professor at the University of Louisville and a Mental Performance Specialist at UofL Health, blending sport science, psychology, and leadership to help individuals and organizations thrive under pressure.
In this episode, Andreas explores the foundation of mental performance—how it’s developed, why it’s often misunderstood, and what separates sustainable performance from momentary hype. Andreas introduces the “existential positive psychology”, a framework that views adversity as a growth opportunity—but only when it’s relevant.
Andreas challenges the idea that mental toughness leads to selfishness. He explains that mental toughness is a personal construct—true strength lies in managing competing demands without losing yourself or others.
He also tackles the corporate tendency to overvalue outcomes and undervalue behaviors. Andreas challenges that mindset, insisting that behaviors are more controllable, more consistent, and more ethical to reward. Andreas also sees potential in how AI can help shape behavior and context if used wisely. He compares it to any other high-performance tool: powerful when used with clarity and care.
This conversation is for anyone who wants to build a mentally tough team, avoid burnout, and embrace the kind of leadership that values people over performance metrics.

Key Takeaways
[03:14] Andreas breaks down mental performance, bringing with real-world examples. Andreas explains that mental performance isn’t about motivation—it’s about creating a “psychological infrastructure” that holds up under pressure, enabling sustainable, adaptable, and ethical performance when it matters most.
[07:16] Andreas delved into existential positive psychology, using Lent as an example: “We do it because we understand that through stress, adversity, difficulty, we grow.”
[09:28] Andreas pointed out what is relevant adversity. Forcing someone to run a marathon when they’re a diver won’t make them stronger—it’ll just derail them. True growth comes from adversity that aligns with personal goals.
[10:45] To counter the perception that psychology is “soft,” Andreas uses data to show that mental toughness is a performance multiplier. His team collects evidence through interviews, questionnaires, and observations, proving that mental toughness improves not only performance but social cohesion and reduces issues like screen time addiction.
[15:27] When asked if there’s such a thing as too much mental toughness, Andreas acknowledged the danger of a “machismo mentality.” While grit is valuable, it can become toxic when it turns into blind persistence that sacrifices well-being.
[19:04] One of Andreas’s most powerful insights came when Jim quoted him: “The entity cannot be more important than the humans that support it.” He critiqued the “performance trap,” where results are prioritized over ethical behavior and people. Andreas advocates for a shift in culture—focusing on the process, the mindset, and the individuals who drive performance, rather than just the outcome.
[24:08] When AI came up in the conversation, Andreas compared it to any high-performance tool: not a replacement for humans, but a servant to human potential. He envisions AI helping people fine-tune their focus, regulate emotions, and stay resilient by providing real-time, personalized feedback.
[31:18] And remember…“Nothing can stop the man with the right mental attitude from achieving his goal; nothing on earth can help the man with the wrong mental attitude.” – Thomas Jefferson
