The thing, when you're down two sets to love, is to stay calm, even though it's hard, because people are freaking out, people are worried for you.

Stay calm and aggressive.

I have to stay calm, cool, and collected.

Romance is tempestuous. Love is calm.

I don't want to think about it because I always want to stay the same, ... I only want to think about next week. I'm happy I've won a grand slam, three Masters Series and five [other] tournaments, but I can't think about that now. I'll think about it at the end of the year.

You have to slow your heart rate, stay calm. You have to shoot in between your heartbeats.
