PATRICIA, 17, SAN CRISTOBAL DE LAS CASAS, CHIAPAS, MEXICO
I discovered what was important to me when I started trying to help others.
I originally applied to teach maths to children for free, but was told there was not enough interest from local children for me to do this.
Then I was telling a woman how I loved art and playing the drums and she said she knew a boy with Down's Syndrome who would love to learn. I volunteered to teach him the drums.
At first, it was weird. I didn't know what I was supposed to do, but I quickly realised he had a lot of potential. I also found that he just knew some rhythms by heart. I worked on teaching him some more rhythms and it became a thrilling experience.
It was very important for me, because I like to be taken seriously, even if I am a minor.
ROLANDO, 18, HOUSTON, TEXAS, USA
The most important things in life to me are my family, my culture, my race, and the world we are growing up in.
Teenagers constantly think about their future and how adults are messing with the world we have to live in.
War is a problem for us young people, our brothers, our cousins, our future children and grandchildren.
Racism is also a major problem today.
I would like to speak to my forefathers, because they cared for the world as if it was theirs. I would ask them how to take care of it, and look at ways that we can avoid wars and stop senselessly killing each other.
MARIA, 15, SALTA, ARGENTINA
What I care about most are international conflicts, as I think our future depends a lot on how they are handled.
I started getting interested in the Horn of Africa this year, when I participated in a United Nations schools programme, which focused on Somalia.
This was an extraordinary experience, as it helped me get to know this country that you never hear anything about.
I started reading about the situation there and I am anxious to keep informed about what's happening in Somalia and the wider region.
Even though I live so far away, it now occupies all of my thoughts.
FABIEN, 17, PUERTO MONTT, CHILE
My life is dedicated to playing PC games.
I started to play when I was 15, and haven't stopped since.
I think it's a good way to relax and have fun at the same time.
I also use it to show that I am good at something, because, even though I try to apply myself at school, I am better at computer games.
ASDRUBAL, 15, SAN SALVADOR, EL SALVADOR
The most important thing in my life is my family.
My parents gave life to me and my sister, and you tend to like them more as you grow up.
My main passion is literature.
I would love to interview [Brazilian author] Paulo Coelho and ask him how he can write such beautiful books.
I also love hip-hop music.
ROCIO, 14, MEXICO CITY, MEXICO
I love music. Music liberates feelings and emotions, there's no bigger pleasure than listening to a good song.
But lately, there isn't any good new music. I just don't think bands put any effort into their music any more. It seems that they only care about money.
Rock and metal bands are not like they used to be. You don't see bands like Pink Floyd, Led Zeppelin, Black Sabbath or The Doors emerging.
I would love to interview Jim Morrison, Jimmy Page, Syd Barret and Ozzy Osbourne, and ask them how they managed to compose such perfect and deep lyrics and such pure sounds.
