Murray, who won three grand slam titles across a glittering 19-year career, saw his time on the court come to an end at Roland-Garros in the Paris Olympics.
The 37-year-old competed alongside Dan Evans in the men's doubles, reaching the quarter-finals of the competition to eventual bronze medallists Taylor Fritz and Tommy Paul.
Murray withdrew from Wimbledon ahead of the Games after picking up a back injury against Jordan Thompson at the Queen's Club Championship, the latest of many injury setbacks towards the latter stages of his career.
"Since I've stopped, I feel really free and have got lots of time to do whatever it is I want," Murray told BBC Radio 4's Today programme.
"I can dedicate time to my children and have free time to play golf or go to the gym on my own terms.
"It is really nice and I didn't expect that. I was expecting to find retirement hard and be missing tennis a lot and wanting to get back on the tennis court on tour.
"So far it has been the complete opposite to what I was thinking."
The 37-year-old won his first grand slam in 2012 at the US Open before ending Britain's 77-year wait for a men's Wimbledon champion in 2013, winning it again in 2016.
During his career, Murray played 1,001 singles matches in his career, earning his landmark victory against Alexei Popyrin in three sets at Queen's.
After his injury in W14, the Scot vowed that the 2024 Olympic Games would be where his career ended, a competition he won two gold medals in 2012 and 2016.
While there was no perfect ending in the French capital, Murray revealed he was now spending some quality time with his family.
"The thing that I always found difficult in recent years was that there was always a guilt associated with what I was doing," Murray said.
"If I was going away for a trip of like three to four weeks I would feel guilty leaving my children at home or being away from my wife for a long time with them, so missing the kids I found hard.
"But if I was at home with the kids then I was running around and spending a lot of my time on my feet after training.
"I was then thinking 'is this going to affect my training or performance the next day, should I have my feet up?' I found that stuff difficult over the last few years."
