In this episode of the Curious AF Podcast, host Luke Biermann sits down with Sabrina Trobak, a counsellor, speaker, and author of Not Good Enough: Understanding Your Core Belief and Anxiety. With years of experience helping individuals uncover the root causes of their struggles, Sabrina brings deep insight into how our core beliefs silently shape the way we think, feel, and live.

At the heart of this conversation is the powerful idea that many of us carry an inner voice whispering “not good enough, not important, not valued.” Sabrina explains how these beliefs often develop in childhood through both subtle and obvious experiences, and how they manifest later in life as anxiety, anger, addiction, or disconnection.

Together, Luke and Sabrina explore practical strategies to bring awareness to these unconscious patterns and replace them with healthier beliefs rooted in self-worth and confidence. Instead of quick fixes, Sabrina shares why sustainable change comes from small, consistent steps that gradually shift our perspective and emotional resilience.

Key Takeaways: 

• Core beliefs like “not good enough, not important, not valued” silently shape our mental health, driving anxiety, anger, and disconnection.
• Suppressed emotions fuel anxiety and unhealthy coping strategies, while awareness and expression are the first steps to healing.
• Addiction often becomes a self-fulfilling prophecy, temporarily numbing pain but ultimately reinforcing negative core beliefs.
• Sustainable change comes from small, consistent steps, evolution, not revolution,  to rewire thought patterns and build self-worth.
• Healthy coping strategies and strong boundaries depend on confidence and self-belief, not avoidance or suppression.
• Awareness practices like journaling, mindfulness, and emotional processing can help challenge old patterns and transform core beliefs into self-worth, confidence, and resilience.

Guest Bio: 

Sabrina Trobak is a registered clinical counsellor, author of Not Good Enough: Understanding Your Core Belief and Anxiety, and founder of Trobak Holistic Counselling. With over 20 years in education and a Master’s in Counselling Psychology, she helps individuals heal past trauma, manage anxiety, and transform limiting core beliefs into self-worth and confidence.
