What No One Tells You About Mentorship

What is a mentor… really? In this episode of You Don’t Know Jack, Dr. Haley Perlus and Dr. Jack Groppel break down what mentorship actually looks like beyond the buzzword. But this conversation is different. This podcast is built on a real mentor–mentee relationship. Jack is the mentor. Haley is the mentee. Every episode is a live, unfiltered exchange of perspective, experience, and growth from both sides of that relationship - something you don’t typically hear. This isn’t a conversation about mentorship. It’s mentorship happening in real time. In this episode, we talk about: * What a mentor is (and what it is not) * The real responsibilities of both mentor and mentee * How to find and approach the right mentor * How to build a relationship that actually works * Why mentorship can accelerate your growth in sport, business, and life This isn’t about waiting for someone to guide you. It’s about learning how to engage, ask better questions, and take ownership of your development. Because the right mentorship doesn’t just give you answers. It changes how you think. If you are serious about growth, performance, and becoming your best, this conversation matters.

Visualization Isn’t Positive Thinking | Train Your Brain Like an Elite Performer

Visualization is one of the most talked about mental skills in performance… and one of the most misunderstood. In this episode of You Don’t Know Jack, Dr. Haley Perlus and Dr. Jack Groppel break down what visualization actually is, why it works, and how to use it to improve performance, build real confidence, and manage anxiety under pressure.

You’ll learn: ✅ The 2 biggest mistakes people make when visualizing ✅ The neuroscience behind mental rehearsal and performance ✅ How visualization builds confidence through evidence, not wishful thinking ✅ Why visualization helps regulate anxiety instead of eliminate it ✅ The difference between symbolic imagery, process imagery, recovery imagery, and preparation imagery ✅ How to actually train visualization like a skill If you want your body to perform, you need to get your mind there first.

How High Performers Manage Fear Under Pressure

How High Performers Manage Fear Under Pressure In this episode of the You Don’t Know Jack podcast, Dr. Jack Groppel and Dr. Haley Perlus explore the psychology of fear and how it affects performance, confidence, and decision-making under pressure. They break down what fear really is, why it shows up when the stakes are high, and how it can quietly influence our thoughts and actions if we let it dominate our mental space. In this conversation, we discuss common types of fear including: • Fear of failure • Fear of success • Fear of not belonging • Fear of judgment and expectation Most importantly, we share strategic tools to manage fear and build the one quality that consistently counteracts it: confidence. You’ll learn how to: • Build confidence through preparation and action • Keep fear from occupying the primary space in your mind • Reframe fear so it becomes information instead of limitation • Perform and lead effectively even when fear is present This episode is for athletes, performers, leaders, and anyone striving for competitive excellence and peak performance under pressure.

episode The Stress–Recovery Cycle: The Missing Link in High Performance artwork

The Stress–Recovery Cycle: The Missing Link in High Performance

High performance cannot exist without both stress and recovery. In this episode of You Don’t Know Jack, Dr. Haley Perlus and Dr. Jack Groppel explore why stress is not the enemy, but an essential part of growth, adaptation, and performance, and why recovery is what allows stress to actually work for you rather than against you. We break down the biology of stress and recovery, explain why burnout happens when recovery is missing, and discuss how elite athletes, business leaders, and high performers can build intentional recovery “doses” into demanding lives. From active recovery and energy management to sustainable performance in work and sport, this conversation reframes stress as a vital signal and recovery as a performance skill. Whether you’re an athlete, executive, or someone feeling stretched by life, this episode will help you understand how to train, work, and live in a way that supports long-term performance, not exhaustion. Topics include: • Stress and recovery as a biological cycle • Why burnout is a recovery problem, not a motivation problem • Active recovery vs passive recovery • How to incorporate recovery into high-pressure work environments • Sustainable performance in sport, business, and life  Subscribe for weekly episodes on performance psychology, resilience, leadership, and mental strength.  To learn more about Dr. Jack Groppel: https://jackgroppel.net/ [https://jackgroppel.net/]  To connect with Dr. Haley Perlus: https://drhaleyperlus.com/ [https://drhaleyperlus.com/]

En fantastisk app med et enormt stort udvalg af spændende podcasts. Podimo formår virkelig at lave godt indhold, der takler de lidt mere svære emner. At der så også er lydbøger oveni til en billig pris, gør at det er blevet min favorit app.

Rigtig god tjeneste med gode eksklusive podcasts og derudover et kæmpe udvalg af podcasts og lydbøger. Kan varmt anbefales, om ikke andet så udelukkende pga Dårligdommerne, Klovn podcast, Hakkedrengene og Han duo 😁 👍
Podimo er blevet uundværlig! Til lange bilture, hverdagen, rengøringen og i det hele taget, når man trænger til lidt adspredelse.
