I have learnt to be even more patient.
I can't stay No. 1 for fifty years, you know. We'll see what happens.
But so far I have the feeling that the chances are there to repeat last year's season.
Early in my career, I struggled with consistency, but I couldn't get more consistent than this year.
I never waited 27 years, because 27 years ago I was just born. My parents never told me, 'If you don't win Roland Garros we take you to the orphanage.'
Previously I always thought it was just tactical and technique, but every match has become almost mental and physical - I try to push myself to move well. I try to push myself not to get upset and stay positive, and that's what my biggest improvement is over all those years. Under pressure I can see things very clear.
