The trouble with me is that every match I play against five opponents: umpire, crowd, ball boys, court, and myself.

Lately, my mind is like an orchestra. If you don't have the conductor, you don't know what to do. One guy is playing jazz, one guy is playing rock and roll, another classical. It's a big mess.

At her birthday, my seven-year-old daughter will say that she wants these big cakes and certain expensive toys as presents, and I can't say no to her. It would just break my heart. But when I was little, for birthdays we just played outside and we were happy if we got any cake.

Winning Wimbledon was a great feeling and it is still a great feeling. It has given me so much confidence.

Although we didn't have much when I was growing up in Split, Croatia, my parents always tried to ensure that my sister and I had the things we needed, and it was enough for us.

There are not many Irish people playing tennis!

While I didn't have everything that I wanted, I was still a happy kid.
