“I'm a very positive thinker, and I think that is what helps me the most in difficult moments.”

“My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.”

“To handle that stardom, the red carpets, the photo shoots, people all of a sudden recognizing you and following you in everyday life, it's a bit weird. It's strange, and it can have funny effects on you in terms of do you like it or don't you like it. Some people run away from it, some people embrace it; I found a good middle ground.”

“I'm a very positive thinker, and I think that is what helps me the most in difficult moments.”

“You always want to win. That is why you play tennis, because you love the sport and try to be the best you can at it.”

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

“I did all the right things in so many tournaments. But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know.”

“I don't need to come back to Wimbledon every year because I can't live without it. I'd be totally cool without tennis.”

“Nadal and Roger Federer have great respect for each other. I think Novak Djokovic gets under those two guys' skin a little bit, and maybe they don't want to admit it, and I think that's, in a way, healthy.”
