Tennis can be a very frustrating sport. There is no way around the hard work. Embrace it. You have to put in the hours because there is always something you can improve. [Y]ou have to put in a lot of sacrifice and effort for sometimes little reward but you have to know that, if you put in the right effort, the reward will come.

One or two years ago, I didn't know who I was on court and I used to swear a lot. But now I've learned how to cope and can therefore win 10 matches in a row. I want to be remembered as a good player rather than an idiot on court.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.

Success is a nice thing because it always means you've taken a step forward and it gives you a sense of pride, which in turn gives you confidence and experience-a positive circle, so to speak.

Winning or losing, it's always something special and something you'll remember, even more so when the match was as dramatic as it was today. It's even more memorable when I see my kids there with my wife and everything. That's what touched me the most, to be quite honest. The disappointment of the match itself went pretty quickly.

Having twin girls is a life changer - that's for sure. But I like getting up and changing diapers. It's the things you do.

I've done so many interviews over the years in so many different languages. Radios. Papers. Magazines. There's always another interview to do. It's quite something, I have to say.
