The former world number one is still in the early stages of his comeback from career-saving hip surgery last January, but pinpointed success in Asia as a turning point in his recovery.
After gaining more confidence during tournaments in Zhuhai, Beijing and Shanghai, the Scot produced a remarkable level of consistency to win in Belgium - his first title since 2017.
Now he is eyeing a return to singles action at Wimbledon next year and five-set success at the Australian Open in January.
“Asia was basically where I started to realise I can do this because at the beginning of that trip, literally two or three days before the first tournament in Asia, I was having conversations with my team,” Murray said.
“I was practising and I was like ‘no, I am giving this until the end of the year and if I’m not winning matches and feeling better than I am now, I don’t want to keep going.’
“I was putting a lot of effort in but my movement wasn’t at the right level, but as I started to play quite a few matches it changed quite quickly and I thought I was a lot further away than I was and that was what a lot of guys in the team were saying to me.
“They were saying ‘you are much closer than you think’ and I won a few matches, started to feel better and maybe as well I gained more confidence in my hip. I stopped thinking about it in matches - which was quite a big step.
“At the beginning you are thinking about it after every movement you make and that is not a good way to go into competing but now I am not thinking about it when I’m playing.”
Murray was speaking ahead of the premiere for a feature-length documentary entitled Andy Murray: Resurfacing which will be available on Amazon Prime Video from November 29.
Following a successful period on the hard courts in Asia, where the double-Wimbledon winner defeated top-10 player Matteo Berrettini and pushed Dominic Thiem close in September, he closed out the season with victory over Stan Wawrinka in the final in Antwerp.
Now he is eager to challenge himself in the longest form, starting at the Australian Open - the scene where Murray finally made public the full extent of his hip problems and tearfully announced he was considering retirement.
He added: “I was asked what would be success in Australia and I don’t know how I will perform - I’m not expecting to win the tournament - but if I can play a five-set match and get through and have no ill effects on the hip then that is success.
“Because I know I will be able to compete in the major tournaments without having to worry about it. “I have played three-set matches and some long ones recently, but the best of five is an extra hour, hour-and-a-half on top of that so I will find out in Australia.
“If I can get through that tournament and get through some long matches potentially feeling good it would be a big positive.”
A strong Australian Open would raise the possibility of Murray competing in the singles at Wimbledon again and even possibly in the Olympics where he would look to defend his gold medal.
On the prospect of competing at The All England Club again, Murray replied: “To play there, yes (I’m feeling positive), but winning? No. I wouldn’t put my money on me to win the event just now, but if I can get there and be pain free, I can do well.”
Although he was only able to compete in one match for Great Britain at last week’s Davis Cup, he confirmed he was “ahead of where I expected to be at this stage” with regard to his hip.
Quizzed on what age he would consider retirement again, the 32-year-old added: “It depends how long the hip lasts basically.
“I could have other injuries on top of that as well. If I am healthy, I’d love to play for as long as I can.”
