There's just nothing like playing on Arthur Ashe Stadium. It's truly amazing.

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

I used to always be the young one playing without pressure, but I am just happy to be where I am and enjoying my time.

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

I'd like to do a lot of things - whether in design or architecture or business.

I have a really wide range of interests and I've still got time to work out my exact direction.

You can't dwell in your past but move forward, look forward. That's it.
