Andy Murray insists he has no regrets about his long battle to regain fitness despite admitting he is still unsure how his troublesome hip will hold up.
The former world number one is in Australia preparing to start the new season at the Brisbane International having managed just six tournaments in 2018.
It was in Brisbane 12 months ago where Murray finally accepted he would have to undergo surgery after trying for six months to overcome a problem that first surfaced in the summer of 2017.
"There's nothing I'd rather do more than stay out on tour. I love the practice, the competition, the locker room.
"I want to play as long as I can. There are still things I want to achieve. Whether I am capable of doing that or not, we'll see."
Murray is likely to play a lighter schedule than in previous years, with recovery a top priority.
He has spent several periods during the last six months in Philadelphia working with reconditioning specialist Bill Knowles, who also travelled to the Scot's pre-season training camp in Miami.
The 31-year-old, who is currently ranked down at 256, said: "I have to be smart with how I train and manage (the hip) as best I can.
"Last year I was in more pain than I am now. It was a hard year in which I went through a lot, but I had to accept that pain was something I had to deal with.
"This time I'm trying to enjoy myself. I missed playing here and I'm going to go out and compete as hard as I can."
British number ones Kyle Edmund and Johanna Konta also begin their seasons in Brisbane while Nick Kyrgios is set to defend his title despite being hospitalised over the Christmas period with a spider bite.
