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.

I am a very positive thinker, and I think that is what helps me the most in difficult moments.

The crowds are very important for tennis. It makes you play better, but it can also make you nervous and that's the beauty of it.

The one thing you can do for sure is push the luck on your side

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.

When you do something best in life, you don't really want to give that up - and for me it's tennis.

One of my big, big strengths I think early on in my career was that I could learn very quickly. You wouldn't have to tell me the things 10 times or 50 times until I would understand them. You would only have to tell me two or three times.
