The most tenacious tryer I've ever seen was Jack Nicklaus. The man's mental attitude and mental stamina is legendary. Peter Alliss was born in 1931 and perhaps he grew up in kinder, gentler times. That may be so but during his professional golf career he was still a most determined competitor. Peter Alliss has become one of the most respected writers and commentators on the game of golf.
Golf is a social game.
You generally play the game in groups, sometimes with friends and sometimes with perfect strangers. There are flights ahead of your group and flights behind your group. You don't play the game in isolation. Every now and again I come across something in this game that stands out like a beacon burning brightly on a cold, dark night. While we all like to take the game seriously and do our very best it is a sad fact that some players just take this too far.
