Maybe I have to work a bit harder on clay. It's a challenge and I've always liked challenges. Whether I will ever win the French and master playing on clay, who knows? But I'll give it a shot.

Grand Slams are different. If you can get through a few matches, the draw opens up and you get confident. You just need a little bit of luck early, you get through those opening matches and you never know what could happen.

Ten minutes? That's the women. It's not for the men; not for the real game, mate.

Even when I was No. 1 in the world, I was taking it one match at a time. I never was a player to look too far ahead, the way draws can pan out.

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

I feel like when I'm match tough and match hard and played a lot of matches I got that competitive winning spirit going and I can get on some rolls like I did last year. I won San Jose, Indian Wells and made the semifinals in Miami so it can happen for me.

That's what you do all the hard work for, to play in situations that put your body through gruelling times. If you're not up to it, pull out.
