Of course your physical appearance allows other people to see that you are Hannah and not your sister Julie. But it's even more important for you to know who you really are. Do you like school? Are scrambled eggs your favorite breakfast food? Would you rather climb a mountain or swim across a lake?
Dr. Adele Brodkin, Ph.D., believes it's important for teens to know who they are in terms of their values and goals. "It's good to know who you are and be proud of who you are, but be humble," she said.

Thirteen-year-old Natasha Pradhan works with kids with special needs at the Special Olympics. She helped one kid overcome his fear of the deep end of the pool. He gained confidence in himself and went on to win second place in a swimming event.
Besides helping the kids, Natasha said they also teach her lessons. She said the kids don't care about winning. If another swimmer wins the race, the kids aren't selfish and they congratulate the winner.
"It makes me happy to know I'm making a difference in someone's life. I see them change with my own eyes," Natasha said.

Fourteen-year-old Lauren Peterson moved to England from the United States when she was just 7 years old. She goes to a school where half of the students are American and the other half are from countries around the world. Since she has lived in England, she has met people from countries such as France, Sweden, and Norway.
Her school even helps the students learn about each other's cultures. A culture fair gives kids the chance to teach other kids how to play games from their country. Students also taste international foods and write their names in other languages. The school also sometimes has special flag raising ceremonies. A country's flag is raised and that country's national anthem is played.
"[The activities] teach you to open your mind and learn about their countries,"
