DUDLEY High School student Makelesi Nasilivata is requesting parents to throw their support behind their daughters.
Ms Nasilivata, 14, is now in her fourth year as a Girl Guide and was part of the celebrations in Suva marking International Day of the Girl.
"Be active in your child's life, especially in a girl's life," Ms Nasilivata said.
"Every small thing they do, thank them for it. Show your appreciation, let them know that they are loved and their work matters."
Ms Nasilivata said one of the factors holding girls back from achieving things in life was the lack of parental support.
"If only older people, especially parents, realise the impact they would have on girls' self-esteem if they learned to appreciate more than judge or throw criticism.
"A lot of girls are growing up now without the appreciation they crave for from their parents and they look elsewhere to fill that void.
"Parents are important; we need them to tell us they love us more."
Ms Nasilivata advised young girls to take advantage of every opportunity that could help take them forward.
"We are not growing any younger. Believe in the things you do and always look forward to the future."
