Scientist, inventor and Unicef Youth Advocate for 2021, Gitanjali Rao, 16, said adults need to recognise the potential of children. “The really great thing about children is that we dream big and we can make those dreams a reality… My biggest message to children around the world is that self-doubt is your biggest enemy," she said. "Don't be afraid of failure, because once you make that jump, then you can tackle the world's problems. And to adults, my message is that belief means more than you think it does." Despite her young age, she has already racked up several notable technological achievements. She has developed a tool for early diagnosis of opioid addiction, has invented a device that can measure the lead content in drinking water and has launched an app that uses artificial intelligence to detect cyberbullying. She counts her parents as her biggest inspiration for teaching her to stand up for what she believes in, and cited Malala and Marie Curie as role models. "I'm so beyond honoured and humbled for this opportunity," she said. "It elevates my voice so I can speak louder and have my voice heard, and at the same time solicit new innovators and new change-makers into this incredible world that is being a young advocate. When youth have their voices heard, more people are willing to adapt, change, and go towards a mission together.” Lebanese singer and Unicef Regional Ambassador <a href="https://www.thenationalnews.com/arts-culture/music/lebanese-singer-yara-is-the-new-regional-ambassador-for-unicef-1.1136807" target="_blank">Yara</a> closed the event with a concert featuring her popular Arabic songs. <a href="https://www.thenationalnews.com/mena/syria/2021/11/20/world-childrens-day-10-year-old-syrian-amputee-hopes-to-become-a-professional-footballer/" target="_blank">World Children’s Day</a> was established in 1954 as Universal Children's Day and is celebrated on November 20 each year to promote international togetherness and awareness among children worldwide and improve children's welfare.
