The "growth mindset," that is, believing that children can develop their skills in order to succeed in life and seeing challenges as opportunities, is essential for children, and a key element of it is self-esteem.

In this book, the four levels of self-esteem, according to the work of psychologist Deborah M. Plummer, are divided into four corresponding chapters. They include activities and games that help children develop their own skills, so they can create a constructive and positive inner dialogue, which will lead them to growth and happiness.
