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.
