In *Oser être*, Agnès Payen de la Garanderie offers a practical personal-development guide focused on the courage to live authentically and build a healthier relationship with oneself. Drawing on her work in sophrology and self-esteem, the book encourages readers to recognize their own worth, accept their emotions, and act with greater confidence in everyday situations. Its tone is supportive rather than prescriptive, making it suitable for readers seeking gentle methods for self-understanding, inner balance, and more respectful relationships with others. The volume belongs to the French personal-development tradition and is presented as an accessible path toward greater self-acceptance and personal agency.
