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 for promoting self-awareness and perception of others, it is not about a superficial Keep Smiling, but much more: every feeling can be perceived as a valuable gift and reveals important insights on the path to better understanding ourselves and others. The following skills in children are activated and strengthened through playful relational work: emotional stability, managing feelings and conflicts, communication skills, self-awareness, empathy, and trust in oneself.
