By growing up at a center for people with special needs, I learned to always fight hard to achieve what I want. In this regard, I was incredibly lucky.

As a child, I was lucky to have the support of my parents because starting a tennis career is a very expensive adventure.

I was a little bit lost in my head after winning a Grand Slam. You're like: 'So what's the next goal? What do you want now? Where do you want to be? It's not a problem if you lose.'

Stress is part of your career. You have to accept it and deal with it because there is a lot of emotion in tennis.

Real Madrid aspires to win everything, and I feel part of the family at this club.

I was really scared to stay home alone when I was kid, and I would freak out whenever there was a noise after my parents left.

You are the mother, the father, the sister, the brother, the teacher and the guide for the soul that has been placed in your trust.

In the case of 'The Book Thief,' my research was hearing the stories of my parents when I was a child. But I started changing the stories when I began moulding the book.
