I always believe if you're stuck in a hole and maybe things aren't going well you will come out stronger. Everything in life is this way.

My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.

I can walk around screaming, 'I have 17 Grand Slams. I have the record here or there.' When you can play for history and you do it, that's what is so really cool, is that you can then be compared to other greats or you've passed another great, even though it doesn't mean you're better than him. But it's just like that moment you've gone into the unknown where nobody else has ever been before.

You can't expect yourself to be already peaking like crazy in an exhibition tournament.

My aim over the next few months is that I have a lot of points to defend in Miami and Hamburg, after that I can set my sights on No. 1.

I'm shocked every time that I've reached so many finals or won against so many players or whatever record it is. It strikes me and makes me obviously very happy and very proud that I've been able to do it for so many years at the highest of levels.

When you're good at something, make that everything
