Novak Djokovic: "What I learned as a young child continues to have a tremendous impact on my life today. I had a unique priviledge to have a good start in life and a chance to develop my talents. But the starting line is not the same for all children. Those born into poverty or on the margins of society require our extra support to realize their dreams. Preschool programs are essential to give every young child the maximum possibilities to success in his further education. They provide them with a winner's starting position."
