I learnt just how little it takes to survive, which is why I don’t waste things – food, money, friendships or opportunities.

If we don't take care of each other, who will? ... I don't want to ever say, 'I should've done something.'

There are models who don't eat. That's worrisome - you need the right amount of gas to get going.

I believe that true beauty comes from inside you and that always shows through. I have no problem with whatever the next look is, whether it's big blonde hair and blue eyes or green hair and dark eyes. That's fine so long as there isn't just one ideal image.

In my country, families are raised as though they are one. Although I am from the Dinka tribe, my parents didn't raise us as the Dinka tribe. They raised us as the Wek family, in the way they believed their children should grow up. So when you leave, the first thing you think is the ones you left behind. It's natural to help them in any way you can. I found a way to support myself rather than asking my Mum to give me money. I would work before school and send money back to pay for their rent and food.

My boyfriend isn't a rock star. His values are rock solid. We met at a dinner and he made me laugh.

Maybe I do have a few more dresses, but I'm just like everyone else.
