Probably around 14, when I was finishing primary school. I'm coming from a pretty small city in Croatia, not too many options to train, not too many players. So I had to either choose to stay at home to do more school or move to Zagreb to the national training center. That was when I made decisions to do something better in tennis.
The most special Slam is Wimbledon, of course. But where I feel the best is Melbourne. And you're happy that you're playing. When you get to the middle of the season, everything is week after week, and it's all routine. But when it's Melbourne in January, you are fresh and you want to play. It's nice.
