Your childhood beliefs about yourself aren't fixed—they're choices you can actively rewrite. Therapist Marisa Peer reveals how repetitive thoughts become your reality, sharing practical tools to upgrade limiting beliefs formed by family dynamics and childhood shame into empowering narratives that reshape your entire life. The subconscious mind doesn't think—it only feels and works to make your repeated thoughts physically real, which is why visualization exercises produce measurable bodily responses like increased saliva or improved flexibility. Childhood experiences create core beliefs like 'I'm different so I can't connect,' 'I'm not enough,' or 'what I want isn't available'—but you can dismantle these by consciously choosing better thoughts and repeating them until your mind makes them real.
