Marisa Peer explains how our subconscious mind manifests psychosomatic symptoms to meet perceived needs, like headaches stopping parental fights or illness garnering attention, based on the harmful words and beliefs we repeat. Having resolved her own fertility issues by rejecting limiting diagnoses, Peer helps women conceive by unveiling childhood messages blocking pregnancy, though the mind simply acts to prevent feared outcomes we claim would “kill us.” Emphasizing that the mind’s role is survival, not happiness, she argues we can reprogram our brains by monitoring self-talk to align with desired rather than default realities. Ultimately, Peer stresses that because negative self-beliefs shape self-fulfilling outcomes, we have the power to transform our lives by speaking constructive truths.
