I think I was as mentally tough as I've ever been. I felt like I handled the situation both on and off the court extremely well. I felt like I needed to.

I'm not a guy who needs to read motivation books.

That's when you've got to grit your teeth and hang in there and try and find a way to win when you're not playing your best tennis - that's what I can be proud of

I'm more in that Rafa Nadal high-energy high-octane mold out there. I wear that emotion on the court. That's how I play my best tennis. People either like that or not. And I can't change that: that's who I am on a tennis court.

I don't know. Haven't I always been mature?

I've probably put up with more criticism than a lot of people out there. At the end of the day, you block out everything, especially with your personal life.
