I don't just want to be someone who hits the ball 100 per cent every time. You can play with freedom and still mix up the pace, mix up the spins and everything like that. That's what I want to be doing, because you get into that very one-dimensional kind of tennis if you don't work on slicing and coming into the net.
I don't remember my first race, but I do recall various school sports days where I became way too competitive. We were seven or eight years old, and I had a very stern conversation with my relay team-mates about how crucial it was for us to win.
I generally don't use an iPod for track work, as I'm focusing on heart rate and times. When I'm in the gym or running alone, there's always music. If I'm in the weights gym, I usually go for rap or rock music; for running, it's dance or cheesy pop.
If there is noise against you, then you try to make it seem it is for you. You just have to try to focus on your own game and try and win the match whatever way you can.
