I was in that period right after I won Wimbledon, ... The next four months, I felt like I had to win every match. It's a matter of telling yourself that it's impossible to win everything ? no matter what people say. You can't control people's actions. My big thing is to just keep working hard. Because one day, you're going to be on court and you'll win a match and realize that the hard work paid off. That's exactly what I did last year. I lost here and I worked my butt off.
