Andy Murray spent years at the top of tennis, reaching No. 1 in the world, lifting Grand Slam trophies, and winning Olympic gold medals. But the Brit has confessed that his entire perspective on his career changed as soon as he entered retirement last summer.

In spite of everything he achieved, Murray confessed that he never had "much pride" in his career while he was still on the tour, and the three-time Major winner now regrets not being kinder to himself during his playing days.

Murray appeared on the latest episode of Romesh Ranganathan's podcast, where he opened up on his major shift in perspective after ending his professional tennis career. The 38-year-old retired at the Paris Olympic Games last summer, joining forces with Dan Evans in the men's doubles.

They made it all the way to the quarter-finals before losing, sending Murray into retirement. And it took just a few days for the Brit to gain a new perspective on his accomplishments.

Reflecting on the end of his career, the two-time Wimbledon winner explained: "I think it helped that I was react to retire, physically I couldn't really play to the level I wanted to anymore, my body was kind of telling me that it was time.

"I didn't feel like I still had much more to give but within like 10 days, two weeks of finishing, I looked back and was like, 'Wow, I can't believe I managed to do these things and achieve these things'."

Murray formed fierce rivalries with Roger Federer, Rafael Nadal and Novak Djokovic throughout his career. And their records left him feeling like his victories paled in comparison.

"When I was playing, I didn't really have much pride in my career because a lot of the times, I was surrounded by three of the best tennis players of all time and your achievements are kind of miniscule in comparison to those guys and you're kind of looking to them, one, to try and learn and improve, but also you want to try and match their results," he added.

"You're having to beat these players, so I didn't have much pride in what I'd achieved whilst I was playing, but very quickly, when I finished, I don't know, my perception of my career and what I achieved changed drastically. It's a shame, I wish looking back I'd been a bit more kinder to myself and enjoyed my career a little bit more. It's hard, when you're trying to achieve things, there's always the next tournament and the next week. There's always pressure to go out there and perform."

Now that Murray can appreciate his tennis career, he has turned his attention to another sport, golf. The former world No. 1 is on a quest to become a scratch golfer, and he's already played a few Pro-Am tournaments at Wentworth and the Alfred Dunhill Links Championship.
