"Golf cannot be played in anger, or in any mood of emotiional excess. Half the golf balls struck by amateurs are hit if not in rage surely in bewilderment, or gloom, or in cynicism, or even hysterically - all of those emotional excesses must be contained by the professional. Which is why balance is one of the essential ingredients of golf. Professionals invariably trudge phlegmatically around the course - whatever emotions are seething within - with the grim yet placid and bored look of cowpokes, slack-bodied in their saddles, who have been tending the same herd for two months."
