Rafael Nadal says it isn't easy to win the French Open ten times, even if he's sometimes made it look that way.
The world No. 1, who will again enter the tournament as the favorite, said his attitude has helped him stay at the top.
"I think it takes a combination of things—a good mentality, a passion for what to do, love of sport, a little bit of luck and finally, the constant desire to improve, to have that on court every day," Nadal told *Le Figaro* in an interview published in French. "During the years, you gradually decline in some things, you have to keep adding [others] to stay competitive. This is for me the key to this longevity and this success—even more at Roland Garros, 10 times."
