Caroline Wozniacki insists she never considered quitting tennis despite her alarming slump down the rankings in 2016.
The former world number one ended 2015 at 17, but trouble with injury and form has seen her plummet to 74th.
However, Wozniacki showed that she is still a force to be reckoned with after fighting back from a 4-1 first-set deficit to defeat ninth seed Svetlana Kuznetsova 6-4 6-4 in the second round of the US Open on Wednesday, the first time she has beaten a top-10 player this year.
And the Dane says she has never lost the motivation to compete at the top of the game.
"I think, you know, when you're home for a big amount of time you realise that life goes on and you kind of get a rhythm at home. I was actually enjoying my time, making the most of the time that I had," she told a news conference.
"I haven't been able to be home for three months in a row for probably over 10 years. So, if I have to look at the positive of things that was a positive.
"But I always had in my head that I just have to keep working hard and I'll come back and hopefully play strong and play well.
"I knew that it's not easy to come back and especially you are going to get tough draws. I'm a player that needs matches to kind of get into the tournament.
"But, yeah, I wasn't thinking about quitting. I mean I know that I have a lot of opportunities, I have a lot of other interests and my life is going to be good regardless. But I'm still young. Hopefully I have a few more years in me."
