My whole swimming career was about training to beat Michael Phelps in any race I possibly could.

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.

When I'm alone in my hotel room in some foreign place, I feel very lonely. Then I tuck into my favourite chocolate - Chuckles or Whispers - for some comfort.

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'm a huge breast cancer awareness advocate because my mom went through breast cancer recently. It really brought our family closer.

I know of no safe depository of the ultimate powers of the society but the people themselves; and if we think them not enlightened enough to exercise their control with a wholesome discretion, the remedy is not to take it from them but to inform their discretion.

I have a lot of respect for PM Narendra Modi, as he works hard day and night and doesn't sleep more than 4 hours. So I am thinking of gifting him chewing gum, as he will chew that and will take rest and take care of his health.

Florence Nightingale was an amazing figure. She created the American Red Cross. She saw the suffering from bad health conditions on the battlefield and in the military hospitals, and she fought like crazy to change the conditions; to make sure that the doctors washed their hands and practiced sanitary measures. She put herself at great risks.
