Elise Choi Ho-yee, 18, Sai Kung Sung Tsun Catholic School (Secondary Section)

I would like to be the speedcubing champion - the person who solves a Rubik's Cube the fastest. Actually, I don't know how to solve it. I tried to learn from my friend once but I couldn't get the hang of how to twist it. She told me to memorise the equations (of which there are many) but I'm not very good at maths. Even though I remembered all the equations, I didn't know how to apply them. Feeling frustrated, I gave up. As a result, I am very jealous of those who can solve the cube, let alone those who break the world record. When I see them on TV twisting the cube at lightning speed, I'm astonished. I reckon their muscles and brain power exceed the average limit of humans. I would like to be one of them and feel the excitement, and be proud that I can do the impossible.

I'd like to have the fastest reflexes in the world. I can picture it perfectly: if someone tried to punch me, I'd be able to coolly dodge blows, like that scene in Spider-Man where Peter Parker evades a punch during a brawl in high school. Faster reflexes would boost my athletic skills, save me from danger, and most importantly, I would look totally awesome - not to mention the fact that I'd basically be a ninja (especially with my powers of invisibility from the last Brain Game round). Unfortunately, my dodgeball skills are absolutely abysmal, so I definitely need to improve in the reflexes department!

To me, "champion" means someone who has a strong desire to make their thoughts known to the world, and wants to reveal a hidden truth about human experiences. I would like to be a champion for the elimination of all forms of discrimination against women. Gender equality is a basic human right because every human has dignity. We are all created the same way. Yet gender inequalities remain deeply entrenched in every society. Women often lack access to decent work and they are frequently denied basic education and health care. Women all over the world suffer from violence and discrimination. They are also under-represented in political and economic decision-making processes. I would like to end all this by achieving equality between women and men as partners of development, human rights and peace and security.

Mizuki Nishiyama, 13, Canadian International School

I would like to be the kind of champion who is satisfied with her life and spends quality time with her family. My family is probably the most important thing in my life. I would put them first before everything else, so if I had to be a champion at something, I would be a champion at making my family members smile and being satisfied with my own life. Being a champion at something means putting lots of work into it to be successful, but if I could magically make that happen in an instant, it would be awesome.

Doris Lam, 15, St Margaret's Co-educational English Secondary and Primary School

"And the winner of the best girls' dream room is ... Doris Lam!" I've always dreamed of redecorating my room or having a bigger room, since my current room is overflowing with things. If I had the chance to redecorate and get a bigger room, then I'm sure it would be perfect ... at least in my own little world. The best thing about my new room would be the library corner. Who needs the public library? I would paint my walls with pictures and quotes that inspire the most, such as "When life gives you lemons, make lemonade". It means that we should make the most out of bad situations. If you give me the chance to redecorate my room, I won't disappoint you - because I'll be the champion!
