Andy Murray said he was satisfied with his past successes to the point where he could retire tomorrow from the ATP Tour and have no regrets.
But the 24-year-old Scot wasn't about to rest on his laurels, especially with a Grand Slam victory still missing from his resume.
"For me, if I had to stop playing right now and looking back to when I was a child I would sign up for my career no question," Murray said Thursday as he prepared for his first match at the Indian Wells Masters tournament.
"I want to try and achieve more than what I have. I am more grown up, more mature and starting to be a power on the court. But I would like to achieve more in my career."
Murray is hoping to avoid a repeat of last year's dismal showing in the California desert, where he suffered a shock upset in his opening match against unheralded American Donald Young.
He has already won once this year in Brisbane and reached the final of the Dubai tournament last month, bowing out to Roger Federer in straight sets 7-5, 6-4. He also reached the semis of the Australian Open.
Murray is making changes to his game, specifically his forehand which he hits with more power than ever before.
"My forehand is a bigger weapon than it was before," Murray said. "It is not a major change but it is very different, especially in the way I move my feet."
