Mangling my racket and an odd swearword on the court is not something I am proud of and it shouldn't happen, but even my coaches have told me that it's sometimes better to let it all out, the anger inside you, because keeping it bottled would just eat you up in the long term.

I think luck falls on not just the brave but also the ones who believe they belong there.

Nobody actually played tennis in my family.

My grandfather went through a lot in his life.

Each year represents new challenges and obstacles. You have to adjust.

I got married, going to become father soon, being No. 1 in the sport that I love with all my heart. I mean, it's pretty awesome.

It is my goal to win every time I play. But on the other hand, I also seek a balance of compassion and respect for the other players. I understand that everyone goes through difficult times, either mentally or physically, to cope with their life, to live the sport.
