Roger Federer says he has greatly exceeded his aims in tennis, although he admits he is 'not sure how' he achieved it.
Federer is arguably tennis' greatest icon, and has been compared to other sporting greats such as Michael Jordan as a rare star who transcends their own sport and enters the cultural mainstream.
In that sense, he is almost unique in tennis, despite the likelihood that his individual records will be beaten by rivals Rafael Nadal and Novak Djokovic.
Looking back on his career, though, Federer says he didn't have any expectations when he started out.
“I'm actually not quite sure exactly why I succeeded as much as I did,” Federer said in for BecomingX in which he answered questions from fans.
“You don't aim for 20 Grand Slams. You don't aim for World number one, not in my world anyway, not in my normal upbringing in Switzerland.
"I'm not sure if we dream this big, you know. It's not something that happens quickly or easily.
"If you're passionate about what you're doing, keep going, keep believing, reach for the stars.
“Surround yourself with the right people and if you really go for it”.
