I feel like when I'm match tough and match hard and played a lot of matches I got that competitive winning spirit going and I can get on some rolls like I did last year. I won San Jose, Indian Wells and made the semifinals in Miami so it can happen for me.

When I go out to play, I still believe I'm as good as anyone out there. I don't have to prove anyone wrong. I know what I've done and how well I can play.

Maybe if you're playing in London or America, you don't feel that pressure quite as much.

Ten minutes? That's the women. It's not for the men; not for the real game, mate.

I am two different people. What you see on the court is just natural for me. I wear my heart on my sleeve. I have always said 'C'mon' purely to fire myself up. Off the court, I am a lot shyer. I stick to my team and my family and people I trust.

Grand Slams are different. If you can get through a few matches, the draw opens up and you get confident. You just need a little bit of luck early, you get through those opening matches and you never know what could happen.

When I was a kid in Adelaide, I dreamed of becoming No. 1 in the world, winning a grand slam and the Davis Cup for Australia.
