I started to travel like this at the age of 15 so for me, it's normal. Some days you get tired and you feel, 'I want to stay at home a little bit more,' but it's only the moment.
Being home alone at night makes me a bit nervous. If I'm at home alone, I have to sleep on the sofa - I can't face going to bed. I'm there with the TV on and all the lights on. I'm not very brave about anything in life. In tennis, yes. In everything else, not very.
I have the same bedroom I've always had. It's clean and tidy when I get home, and after two or three days it gets messy and my mother nags me.
I have no interest in becoming a tax exile and living somewhere I don't want to - I just want to be at home with my family.
I am very lucky because when I come back home, I have a completely normal life. I can relax, playing golf, fishing - doing what I want. I know when I finish a tournament, I am going to relax at home.
