Newsround has been taking a special look at the world you're growing up in.
We've been chatting to seven kids from around the world - one from each of the seven continents.
They're sharing their hopes and fears, and telling you about their lives.
Amani, 11, lives in Kenya, Africa. This is his story.
"My favourite subjects at school are history and maths. In my spare time, I love playing cricket and I'm not bad at football.
I really like playing the guitar and get involved in a lot of church activities. Right now, I am preparing for my baptism.
When I grow up, I want to be a lawyer. I like defending people and I think there are two sides to every story.
I feel very lucky because my area is really nice and free of crime.
The main thing that worries me is that kids are being abandoned because of diseases. The adults who have children are often not prepared for them.
There are too many children in Kenya who have no one to look after them.
The worrying thing for children in Kenya is HIV. It's destroying so many people's lives and the problem is getting worse and worse.
My role model is my dad because he has always worked really hard and tries his best for his family.
Another worrying thing is the amount of pollution in Nairobi. There's so much litter in the city and it seems no one can be bothered to clean it up.
I do my bit by making sure I pick up litter and asking my friends to do it too. But sometimes they are lazy, and don't do it.
If I was in charge of the world and could change one thing I would make sure that every child in the world had a chance to go to school - even if it meant building a lot of small schools.
In Nairobi, many children can't go to school.
The most important thing in his life is my community. They give me self confidence and I'm able to help those around me."
