I enjoyed a close relationship with my mother, who set a wonderful example. As such, I have always tried to be as open and honest as possible with the girls growing up. I let them know they could always come to me with anything - and I would be there to support them.

I loved Diahann Caroll growing up. I love a sophisticated, classy woman.

My mother was a very amazing woman. She was a very strong, remarkable woman.

I think that everybody, at one time or another, has been betrayed and lied to, and it's about the pain, and it's about the healing process, and it's about how do you get past that and move on.

The truth is that since childhood I had cultivated an existential independence. It came from perceiving the adults around me as unreliable, and without it I felt I wouldn't have survived. I cared deeply for everyone in my family, but in the end I depended on myself.

There are days when I still wake up angry, and no one handles it perfectly all the time, but honestly, I feel lucky to have diabetes because of the people I get to meet. The families, the kids, the parents, the other athletes. If I could pick a club to be in, this would definitely be it.

To a father growing old nothing is dearer than a daughter.

Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself. Taking time out with family and friends helps to maintain the work-life balance everyone needs.
