The love and passion for the sport,...
...that's the main source of energy that I get for tennis.
Obviously, my family and my closest team of people inspire me to keep on going.
Of course, the fans.
There is always motivation out there; you just need to look for it.
You just need to feel it.
I did achieve my lifetime goals to be number one and to win Grand Slams.
I feel like there's a lot more that I can do.
As long as there is this flare inside of me...
...and love for the sport, I will keep on going.
I am 28 years old.
I am at the peak of my abilities, and I want to keep going.
