“I don't have a doubt that if I wanted to win Grand Slams, I would commit. I'd train two times a day. I'd go to the gym every day. I'd stretch. I'd do rehab. I'd eat right.”

“I've always wanted to play Davis Cup. I love Davis Cup.”

“It's just the story of my career, really. I will have good weeks; I'll have bad weeks. It's just a roller-coaster.”

“There is a constant tug-of-war between the competitor within me wanting to win, win, win and the human in me wanting to live a normal life with my family away from the public glare.”

“For me, it's an easy way to make money. I'm just hitting a ball over a net. Of course, I've grown up with it. It's a part of me. It's all I really know how to do.”

“I feel like the off-season, for me, is not about getting on court and trying to improve or get better. I want to completely step away from the game and, like, really just enjoy my time at home.”

“I feel like I'm one of the best players in the world tactically.”

“I've been entertaining since I was kid.”

“I play enough tennis during the year; I'm sick of it by the time I get home. So the last thing I want to do is go out there and hit more balls.”

“I'm not dedicated to the game at all.”

“I have 'Focus' on my phone, and I watch it every time I have a flight. Best movie ever... it's because of Margot Robbie, by the way.”

“I just have to go out there and play the right style of game and believe I can win.”

“I think at times I get treated a bit unfairly, but then so do other athletes in Australia, and I feel like things can change.”

“I get so angry. I just go through so many different patches in a game. It's so hard for me to find that balance. It's a tug-of-war all the time.”

“It's important to find a balance between Pokemon and training.”

“I wouldn't say I'm satisfied with my career.”

“I think when things get tough, I'm just a little bit soft.”

“I think Canadians support their athletes a little better than the Australians do.”

“I was playing basketball at Lifetime Fitness every day for two hours. Like, I played an hour of basketball before I played David Ferrer in the semi-final.”

“I think if I have a lot of positive energy out there, I'll be fine.”
