Rafael Nadal insists it is 'impossible' to be a champion without a passion for tennis, but says there is no magic advice he can give.
Nadal is chasing a record-equalling 20th Grand Slam title at Roland Garros, and absolutely obliterated Mackenzie McDonald 6-1, 6-0, 6-3 to move into the third round of the tournament.
It was his 95th win at Roland Garros, and he has how won his last 25 matches on his beloved red dirt of Paris.
However, he says there is no magic formula for success in tennis, although there are two prerequisites.
"There's not one tip as to how to be a champion, there are a couple of things that you have to do well," Rafael Nadal said after the win.
"First of all, you must have the passion for what you are doing. If you don't feel the sport and have passion for tennis, then it's almost impossible.
"You have to be around the right people and find the people who are going to help you in a positive way every day."
Nadal was in particularly brutal form against McDonald, so good in fact that even he couldn't help but be pleased with it.
"My objective is to play as well as I can," Nadal said. "It was a good match for me today. I'm very happy."
