"I'm trying to enjoy the moment and also utilize this time of my career. I'm feeling confident and physically fit," said Djokovic on Sunday after a gritty three-set triumph over Andy Murray in the Miami final.
"I'm trying to use that. That's what I'm thinking about right now," added the 27-year-old Serb, who goes into the European claycourt season highlighted by the French Open having won the three biggest tournaments of the first quarter of the year: the Australian Open and both the Indian Wells and Miami Masters.
"I am aware that this cannot go forever," said Djokovic.
"There is going to be eventually a change of generations, some players that are going to start playing better and be stronger.
"But until that time comes, I'm going to try to stay as long as I can on the top and fight for the biggest titles."
With 4,000 points separating him from Federer at number two in the world, Djokovic is poised to finish at number one in the world for the fourth time in five years.
His 22nd ATP Masters victory is just one short of Roger Federer's 23 on a list led by Rafael Nadal's 27.
Djokovic became the first player to sweep the back-to-back titles at Indian Wells and Miami for a third time.
It's the kind of achievement that he says fuels his ambition.
"Of course I do pay attention of that," he said.
"Any kind of achievement that goes into history books I'm hugely proud of and I appreciate it very much, because I work hard for it and I do cherish it."
Djokovic's victory in Melbourne was his eighth Grand Slam triumph and his first since becoming a father and husband last year.
He says having a family had added a new dimension to his successes on court.
A rigorous fitness regime allows him to play at a high level tournament after tournament, while coach Boris Becker has helped him hone his mental game.
He needed all of his physical reserves in punishing heat and humidity against Murray.
But after a second-set dip in his energy level he roared back for a 7-6 (7/3), 4-6, 6-0 triumph — his seventh straight win against the Scot.
"I managed to, again, rely on the energy supply that I have in my legs and my fitness to basically hold on and make it all the way through the match (to) play the third set the way I have played, like I haven't really been exhausted too much even though we played over two and a half hours."
But fitness isn't everything, Djokovic said, especially on the game's biggest stages.
"Obviously tennis is an individual and very complex sport," he said. "It requires a right balance between the physical preparation and mental strength and emotional, I would say, calmness and self-belief.
"You kind of holistically need to approach it and be at your top"
