I have proven people wrong so many times. I was told when I was younger there is no chance I will make the top 100, top 50, top 30. Every time I have proven them wrong. It's kind of nice.

The only one I feel pressure from is myself to go and give my all for every match and, obviously, I'm a competitor.

To be the world No. 1 has always been a dream for me.

I think I'm a really tough player.

My parents paid me small amounts for cleaning my room or cleaning the dishes and stuff, but I never really had a real job before I started on my professional tennis career.

There are so many tough opponents out there and tough competitors so I've never liked to look ahead.

I just go out there and fight for every point, and then we see how far I can go.
