I get some letters from a lot of people. Sometimes it's nice, with letters from kids or from parents of kids who want to be tennis players, but I also get racist letters. It's really painful to receive something like that because you're not ready for that. You think to yourself, 'That's really bad.' But I realise that there are people like that.
I think Roger Rasheed is helping me to be more serious. Also, he can convey his passion for tennis. He loves the game. Also he's enthusiastic about everything, about tactics, about what is happening on the court, and also physically he's really pushing me. He wants me to do my best every day.
