"You have to play that way. Just spending time on tour is not good enough."
A 10-time finalist on the All England Club lawns, Federer swatted away suggestions he may bypass Paris - as he did last year - to have another big crack at landing an eighth Wimbledon crown.
"I don't see that, because now we have an extra week on the grass, so I don't see myself skipping the French," he said. "My goal needs to be to stay healthy, so when I do go on court that, really, it's a highlight.
"I know you can't make 25 tournaments a highlight, but you can make 15 a highlight, and really be well prepared for those and enjoy it in the process.
"I have a month now until the tournament in Dubai comes around, so that's going to give me some time to reflect and see how I will attack the rest of the season."
In wiping out Tomas Berdych, Kei Nishikori and Stan Wawrinka, before toppling Rafael Nadal in the Melbourne Park final on Sunday night, Federer became the first man since Mats Wilander at the 1982 French Open to beat four top-10 rivals en route to a Grand Slam title.
"It was definitely special on so many levels," Federer said, of his 18th major win. "Being the oldest guy to win the Australian Open for some time now, that's maybe almost the least of things that I think about.
"I see the comeback [from six months out of the game] as a such a beautiful thing. Then I see the epic match with Nadal, playing three five-setters during the tournament, I never thought that my body would be able to handle that.
"And then just beating these top-10 players along the way, that just makes this a super special tournament and one that I'll remember maybe the most."
The 35-year-old said his Open victory was also a reward for perseverance.
"Even though I didn't win Slams the last few years, I'm happy that I played tennis that personally I enjoyed," he said. "I played attacking tennis, I was coming forward, I was making plays.
"That made me happy, even though I lost some times."
