"What is the single most important quality in a tennis champion? I would have to say desire . . . "
"I asked my doctors if I'd be able to play tennis. They said I could. That made me very happy since I haven't played in five years."

"When the modern racquets and strings took hold in the pro game, there became one prevailing game of play: Grip it and rip it. Power greatly increased, but at the cost of creativity. The repetitive baseline bashing left many fans mourning the loss of variety and artistry. Lately, however, touch and finesse have been making a comeback . . . amplifying the quality of shot-making . . . [with] such players such as Roger Federer and Andy Murray [who] manipulate the ball with delicate drop shots, wicked slices, heavy topspin, short angles and flat rockets."
"Play tennis without fear of defeat, and because it's fun and you enjoy it, or don't play it at all. There is no disgrace in defeat. The only disgrace is in quitting in or "dogging" a match. There is no disgrace, no blot on your escutcheon, in admitting that there are players who can beat you, either in a match, in a set, or on any given shot. You don't have to try and prove it was an accident. In the first place, nobody believes you, so you simply appear ridiculous, and in the second place, nobody cares but you, and you know the truth. All these alibis and explanations take your mind off the really important thing, which is, or should be, your match. If done to excess, this sort of thing will destroy your concentration, and bring about the very thing you fear, defeat." 
"Without suffering, there is no happiness."
