The inner critic is a voice that criticizes us, making us feel inadequate and ashamed. It can have different themes like imposter syndrome. To overcome it, we should pay attention to its messages, write them down, and share them with others. Challenging the inner critic by speaking life into each other and choosing to believe positive voices can help. Even with negative feedback, we can grow and take responsibility. Externalizing the inner critic's message and seeking support can lead to more freedom.
