Mentally, I'm not ever going to go away.

Success is a nice thing because it always means you've taken a step forward and it gives you a sense of pride, which in turn gives you confidence and experience-a positive circle, so to speak.

Sometimes I am a different character in different languages. I have different enjoyment from them. Sometimes different answers come out of me. Like, I didnt even know that about me. I get to know myself through different languages, actually.

I always believe if you're stuck in a hole and maybe things aren't going well you will come out stronger. Everything in life is this way.

I don't know how you can go through a four-hour match with Rafa and he never gets a time violation.

I never expected i, in the first place, when I started playing tennis, that I would ever carry the flag into the Olympic Stadium for an Olympic Games... So for me that was a surprise and a huge honor in my life to be able to represent Switzerland.

It doesn't need to be the same every day, doesn't need to be the same shower I use, the same restaurant I go to, the same hour I go to sleep. I've always been very flexible. I don't care if I practice at nine in the morning or 10 P.M.
