To find the answer to this question, this documentary will peer into the lives of a young Zambian boy and confident Iranian women who are breaking new ground.
Patson, 10, lives in Zambia in the southern area of Africa.
The young boy believes in the old Zambian saying, "Anything is achievable through hard work."
So Patson makes an effort every day reach his goals.
Bron in Chipata, which is 500km from Zambia's capital Lusaka, his family was too poor to send him to school. But with the help of an uncle, he was able to move to Lusaka.
But moving to a big city became a lonely experience for him.
Struggling with poverty and loneliness, Patson found a strand of hope.
He was selected to join the Zambian Youth Taekwondo Demonstration Team as a part of the Sports for Hope program funded by the IOC and United Nations.
Through Taekwondo, Patson learned how to act around adults and respect other people.
And it also made him more aware of who he was and what he wanted in life. Now he talks about his hopes with confidence.
He vows to become a member of the Zambian National Taekwondo Team and win a gold medal in the Olympics to bring hope and joy to his people.
Susan, 22, lives in Iran, which was once the center of the Persian Empire.
She likes to buy hijabs to add to her collection at home.
Non-Muslims might find hijabs a hassle to wear but Susan and other Iranians like her wear their hijabs proudly.
Susan also loves Taekwondo and practices it at a high level.
Most sports do not allow female athletes to wear a hijab in competition but Taekwondo permits athletes to wear them, in respect to the cultural traditions of Islamic countries. This allows Muslim women to compete in international competitions.
Susan won a gold medal at the 2011 Asian Qualification Tournament for London Olympic Games that gave her a slot to compete in the London 2012 Olympic Games, making her the first Iranian women to do so.
Her father was an enthusiastic practitioner of Taekwondo and it was through him that she learned Taekwondo. He urged her on when she found it difficult to keep her focus on the sport. Susan says that Taekwondo means everything to her and it's the love of her life.
Susan has a dream.
She wants to participate in the Olympics while adhering to the spirit of Taekwondo that emphasizes tolerance and respect. It's her way of embodying the Olympic spirit of peace and world harmony.
