I started to really believe in myself, and my abilities, when I won the World Under-10 championship in Doral, Florida. I was nine and saw for the first time that I was amongst the best players in the world for my age. This was a massive confidence-builder for me.

I believe that anybody with Mandela's capacity to endure hardship and then forgive is a born leader and example to us all.

Everything is firing on all cylinders for me.

I realise that every time my face is on TV or I'm playing in a tournament, that I am a role model for a lot of people and a lot of kids do look up to me. I try to do my best in that regard and put myself across as honestly and as modestly as possible, as well.

In a serious sense, wanting to change something from the past doesn't work for me - change something you don't enjoy now rather than regretting it later.

I’m three legs toward completing the career Grand Slam at 25. So, I’m feeling pretty good right now.

I expect big things from myself but as long as I can keep the commitment and dedication and put the hard work in, I don't see why there's any reason not to handle it OK.
