Nada Ignjatovic-Savic worked for over 30 years as a developmental psychologist at the University of Belgrade in research and teaching. As a co-founder and director of the Center for Nonviolent Communication Smile Keepers, her stated goal was to raise awareness among people for confident action – both towards themselves and others. In her program aimed at promoting self-awareness and perception of others, it is not about a superficial Keep Smiling, but much more: Every feeling can be seen as a valuable gift and reveals important insights on the journey to better understand ourselves and others. The following skills in children are activated and strengthened through playful relationship work: emotional stability, managing feelings and conflicts, communication skills, self-awareness, empathy, and trust in oneself.
