"To win Grand Slams you have to be in the right frame of mind, the right physical shape."

One must know the so-called 'lesson of a downpour. A man, caught in a sudden rain en route, dashes along the road not to get wet or drenched. Once one takes it for granted that in rain he naturally gets wet, he can be in a tranquil frame of mind even when soaked to the skin. This lesson applies to everything.
