Key Core BeliefsCore Beliefs are the most deeply held, key beliefs we have about ourselves. They can exist consciously or subconsciously, and they substantially shape our perceptions, thoughts, emotions, and actions. We accept these beliefs as true because they are based on our accrued experiences. For example, someone who routinely takes in stray dogs or volunteers might reasonably have the Positive Core Belief, “I am generous.” However, many beliefs are inaccurate and untrue Negative Core Beliefs. These beliefs disrupt our lives. Resolving negative, mistaken self-beliefs is central to helping us lead happier, healthier lives.
