Nadal brushed aside Dominic Thiem 6-4 6-3 6-2 on Court Philippe Chatrier to add to his record haul at Roland Garros.
The Spaniard will remain world number one rather than Federer following his latest triumph in Paris, where he became only the second player to triumph more than 10 times at the same major - Margaret Court being the other.
Nadal showed he still has a burning desire for success at the age of 32, but said he is not motivated by chasing down long-time rival Federer.
He said: "Let me enjoy this title. No, no, no, I can't - I can't be always thinking of more. Of course, I have ambition, of course. I have passion for what I am doing. But I never have been crazy about all this kind of stuff.
"No, you can't be frustrated always if somebody have more money than you, if somebody have a bigger house than you, if somebody have more grand slams than you. You can't live with that feeling.

"You have to do it your way and then you have to be happy with the things that are happening to you, because if you are looking next to you, you can be frustrated thinking that people have more things than you in general terms.
"I am not this kind of person. I am happy that other people have things, and I am very satisfied, and I feel very lucky with all the things that happened it me.
"Of course I would love to have 20 like Roger in the future or even more, but being honest, is something that is not in my mind. What is in my mind now is I won a very important title for me.
"I added one more grand slam, 17 is an amazing number. I feel very lucky to all of the things that have happened to me.
"I am enjoying that moment and that doesn't mean that I will not keep fighting for give me more chances in the future, in the next tournaments, Grand Slams, Masters 1000, 500, 250s.
"I play for my happiness, and I know that I had already, yeah, an amazing career. So I just am just going to keep fighting for things and that's it.
"No, no, no, no obsession or thinking about this kind of stuff."
