A long year has taken its toll on some of the world's best tennis players but the relentless Novak Djokovic gives no indication that he is about to slacken the pace.
He heads to the season-ending ATP World Tour finals in London with a 6-2 6-4 win over second see Andy Murray at the Paris Masters on Sunday in the bag.
The world number one is now first man to win four titles at Bercy and also the first to win six Masters titles in a season.
While Roger Federer and Rafa Nadal faltered in the third round and quarter-finals respectively a few days after playing the final in Basel, Djokovic cantered through the rounds on the banks of the River Seine.
In truth he was tested only by Stan Wawrinka in the semis.
"I will continue to do what I'm doing so far. There is no reason for me to decrease the pace of the training and preparations and performances," Djokovic said.
"It's the last tournament of the year, a very big tournament where I have done very well in the past."
Djokovic has won the last three editions of the season's finale that features the year's eight best players and Sunday's performance suggested it will take an exceptional performance to topple him at the O2 Arena in London.
Yet the Serb insisted: "I try to take nothing for granted. The only way I'm managing to stay successful is by continuing to improve.
"I'm not trying to keep the status quo, because for me that's a regression."
Right now, all stars are aligned for Djokovic, a happy man and obviously a happy player who won three of the four grand slams, losing only in the French Open final.
"I'm a married man, and I'm a father, as well," he said.
"I think I have a nice balance and serenity in private life that reflects on the professional life, and vice versa. I have this belief that the holistic approach will definitely get the best out of yourself."
There is no shame in losing to Djokovic, yet Murray believes he needs to be more competitive when he faces the world number one.
The Scot, seeded second at Bercy, was humbled in straight sets in the final and never looked like he could disrupt a well-oiled machine.
"Since the beginning of last year, my results against him and Roger (Federer), from my perspective, haven't been good enough. I need to do better in those matchups," he said.
"Obviously it's harder playing against the best player than someone that's ranked eight in the world. Those two are two of the greatest players of all time, so there is no disgrace in losing to them.
"But I do feel like I need to start doing better in those matchups, because the scoreline in the last couple of matches there hasn't been good."
