Developing Balanced Core Beliefs

2. Develop a Balanced Core Belief . Now it’s time to develop an alternative core belief to replace your old negative one. When developing a new core belief, you want to aim for something that is more positive, balanced, and realistic. Think of something that is a more accurate reflection of yourself. It is important that the work you do on your
