Despite having been written off numerous times in recent years Federer, who will turn 32 in August, has continued to defy expectations by repeatedly challenging for some of tennis' biggest trophies.
And he has every intention of doing so in the foreseeable future.
"It really is great how happy I've been playing for so long," he said at a special media session organised by Credit Suisse in Singapore when asked what keeps him going after having achieved almost everything the game has to offer.
"People always think everything has to fade away eventually, but I'm not 80-90 yet. I still feel like I'm very young and I know that tennis won't last for ever. So might as well make the best of it while it lasts. Plus I really am playing great tennis, I really am playing the best against the best , sometimes losing, [but] that's fine.
"But as long as I feel I'm right there, then it's easy to wake up in the morning. Maybe it becomes a bit complicated when you don't want to hit the practice courts any more, but I've just come out of a lot of practice last month and it was no problem."
The 17-time Grand Slam champion is coming off a fantastic year in which he managed to achieved all his stated aims.
"Last year was a great season - I achieved all my goals. I wanted to get back to world number one, which I did, won Wimbledon - one of the most special tournaments out there, won an Olympic silver medal. I'd hoped for a gold, but I was looking for a medal and I got it, so I was extremely proud.
"I hope I can keep it up. Longevity is the word here that I'm looking for. I'll hopefully keep on playing for many years because I love the pressure of playing the new generation, improving quickly. I have to work harder to stay at the top and stay with the best.
"I don't mind the travelling or the extreme movements we have these days. It's ok for me, so I'm looking forward to a great year."
The Swiss also admitted that far from being a distraction, his three-year-old twin daughters had allowed him have a lot more fun off-court and also credited his wife for enabling him to continue playing at such a high level.
"I really enjoy my life on tour. My wife is super supportive which is very important. Without that, it would be much more complex. My kids are amazing. I never, ever pictured myself playing the tour while I have kids, but then I got two so that was a big surprise for us.
"But it's so much fun now and I don't mean to see them as a distraction in any way. I want to try to be the best parent I can be.
"So it's really nice for me to see myself like that. I'm going to make it last as long as I can - that's the goal anyway, not just fizzle out, not just play 25 tournaments - play every week and not see my family."
Federer has come out with a significantly lighter schedule this year. At the time of writing, he will participate in only 14 tournaments through the year including the four slams and seven ATP 1000 Masters tournaments. The total number could go up to 15 if he qualifies for the year-end Barclays ATP World Tour Finals in London.
Even though he is still enjoying the grind of the circuit, the 31-year-old admitted he would continue listening to the demands of his body to prolong his career and play at the level that has brought him so much success over the last decade.
"I think it's key to always have a healthy schedule. It's difficult to do it because it's spread out basically from January to October/November so it's hard to say I'm going to take a month or two months off, practice hard while there's 10-15 new tournament winners.
[But] I've never been scared to take those decisions - I've always said in the long run I want to stay healthy, I want to enjoy and have fun.
"I want to be eager and excited and motivated coming back to the tour and not be like 'oh no another trip', 'another meet and greet', 'another fan who wants a picture'. I want to be excited about going on the Center Court, going on the practice court, going into the media room. I want to be fresh for those things.
"For that I really need to get away from it all, which I've done for the past two or three weeks after an incredible South American trip [for the Roger Federer Gillette Exhibition Tour] and before that an incredibly busy year. So it's important for me to have family time and all these things this year.
"I've always played the schedule according to my body, what it can take, my mind, what it can take. I've taken many good decisions and also many bad ones - but over all the years you try not to make the same mistake again.
I'll see how it goes. If I don't play well, I can always play more - enter extra tournaments. [But] I'm not a fan of entering too many tournaments and making fans believe I'm going to show up when I know there's only a 50% chance or 20% chance. I like to make sure the fans know what is happening."
Federer has not entered any tournaments leading up to the Australian Open which begins on January 14. If he wins, the Swiss will surpass Andre Agassi's Open era record of four titles.
'[These days] Records these always happen to be around in some way, shape or form if I do play well. So I don't think there's a motivation right here, right now but when I get close to it and then the media reminds me, it's very inspiring.
"Then maybe I forget a little bit about rivalries I have with certain players and about the great fans I have supporting me, but then I have another element coming into play which then might give me that extra little kick.
"So I hope I put myself in that position so that we can talk about it down the stretch this year."
