Thing is Rosie, and do not disagree with me on this one because you know I am right: Nole is not happy as #7 or #8 in the world and he definitely does not think like Nalbandian.
Nole's happiness totally depends on his performances, and in his case, Happy Nole = Nole with title / reaching later stages of major tournaments = Nole with high rankings.
Actually I don't agree with you at all
I don't think Nole's happiness is defined by his tennis ranking at all. He's not some kind of tennis robot who thinks only of tennis matches and practicing all the time - he's a very well-rounded person who loves his football, his golf, his opera, his family, his music (
), learning new languages, meeting new people, reading, getting somewhat involved in politics and social issues etc. And I feel as long as he has his family, and Jelena and his friends and enough to occupy his mind, then those are the things that make him happy
