I'm definitely open to change, but at the same time I am quite stubborn.

Davis Cup, you know, does take a lot out of you over the weekend. It's tough, especially if you play all three days.

I bought a Ferrari...and then sold it after a couple of months.

I understand how much everyone wanted to see a British winner at Wimbledon and I hope everyone enjoyed it. I worked so hard in that last game. It's the hardest few points I've had to play in my life. I don't know how I came through the final three points... that last game ... my head was kind of everywhere. That last game will be the toughest game I'll play in my career, ever.

I'd like to say that I am romantic person, but I don't think I am. When I won my first tournament I went into the crowd and kissed my girlfriend. I was 18 and didn't have my coach with me, I was there on my own, and I just needed to celebrate with someone I knew. I always start out with good intentions. I'll say something nice, then I'll just put my foot in it and ruin the moment.

I first had money for investment just at the time of the 2008 crisis and shares have been highly volatile since then. So I do have shares in my pension but I have tended to invest in specific projects that include property and private companies that have been very well researched by my advisers.

You have to go into each match believing you can beat all of the players.
