“I have tried all my life to be who I am. That’s one of my mottos really, not pretending to be somebody else. I think that kind of character and strong position got me to where I am,” said Djokovic on Saturday “I still feel that I am enjoying what I am doing, and I try to have fun wherever I go and as much as I can. Maybe tennis lacks that little bit of enthusiastic part of it.”
