Perfectionism leads to a vicious cycle of constant pressure, fear of failure, and negative self-talk. Instead of enjoying achievement, the fear of mistakes dominates, leading to tension, stress, and even health problems.

The roots of perfectionism often lie in childhood, shaped by excessive parental expectations, academic pressure, or negative experiences. Understanding one's own history is essential to overcome perfectionism.

The book provides concrete strategies and exercises to let go of perfectionism, including self-acceptance, realistic goal setting, mindfulness exercises, and the courage to make mistakes. It emphasizes finding a healthy balance between ambition and relaxation.
