I would like to believe there is a God, but I think it is better to say I'm not sure there is a God and live your life with kindness and respect for people than to say I know there is a God and then do bad things.

Is only a tennis match. At the end, that's life. There is much more important things.

The bad thing about the [tennis] calendar is how it is made and obligates you to play tournaments all year. If you want to achieve the most you can (and) go as high up (in the rankings) as you can, you have to play from the start to the finish because there are important tournaments from the beginning to the end.

I've stayed calm when I'm winning and I've stayed calm when I've lost. Tennis is a sport where we have a lot of tournaments every week, so you can't celebrate a lot when you have big victories, and you cannot get too down when you're losing, as in a few days you'll be in the next tournament and you'll have to be ready with that.

I will work day after day like I did my whole life ... I'm not going to change anything.

I have no sense of humor about losing

I am not the most courageous guy in the world outside of the court.
