The author of the text struggles with impostor syndrome, a feeling of being a fraud and doubting their accomplishments and talents. They apply principles from cognitive behavioral therapy (CBT) to overcome this anxiety, particularly by confronting negative thoughts and behaviors associated with it. The author creates a "brag sheet" to record and reflect on their work and feedback, which helps challenge the underlying beliefs that lead to impostor syndrome. By doing so, they reduce stress and improve confidence, but acknowledge that overcoming this feeling is an ongoing process.
