I want to get faster every year, keep my confidence high, so I can continue dominating my main events and extend my range to other freestyle and medley races.

What I want to say is that nobody is unbeatable. There's a kid out there who probably wants to beat me. I train hard and try to be the best that I can be, but I don't disrespect my opponents. I am not disillusioned, either.

I believe now that I've cemented my spot as the best swimmer in the world, and I can't describe how proud that makes me. I just want to keep working hard and hopefully just inspire more youngsters to keep swimming and encourage South Africans to become a winning nation.

The reason swimming is one of the hardest sports is because you have to be in the pool by yourself every day, making that sacrifice. There's no time to do anything else.

I wasn't used to all these cameras getting stuck in my face. I feel like Justin Bieber sometimes.

I realise every swimmer has a shelf life. No, I haven't given any thought to when I will retire, but I also know I won't be able to swim forever.
