The Olympics is not for tennis and tennis does not need the Olympics. It is not my goal in life to win a gold medal.

I pay the bills, I pay for everything.

It's too many questions about what I'm going to do, why I'm retiring, and this and that. So I answer the same question, I don't know, a thousand times.

'I think as a guy you need a little bit to be on your own from early on, to start to live your own life, and try to understand what is going on around you, you have to be able to survive...

It's a completely different situation right now because last year it was the time that nobody expected anything from me anything -- I had nothing to lose, basically I was starting from zero. And now I'm back in Top 5. And for me it's a different stage.

I achieved what I want to achieve and I want to continue doing something else.
