In this HBR IdeaCast podcast, the focus is on perfectionism, distinguishing between the healthy pursuit of excellence and the harmful effects of extreme perfectionism. Clinical psychologist Ellen Hendriksen shares insights on how perfectionism is becoming more common, often stemming from an overemphasis on self-worth tied to performance. She highlights the negative impact this mindset can have on both mental and physical health. Hendriksen suggests moving away from strict "inner rule books" and instead adopting values-based approaches, underscoring the importance of embracing mistakes as essential to personal growth and well-being rather than striving for unrealistic perfection. To illustrate different perspectives on perfectionism, the podcast draws on examples from the careers of Walt Disney and Fred Rogers. Listeners come away with practical strategies for addressing perfectionistic tendencies and nurturing healthier work habits and relationships.
