“In no other walk of life does the cloven hoof

so quickly display itself. Golf is the infallible test.

The man who can go into a patch of rough alone,

with the knowledge that only God is watching him,

and play his ball where it lies, is the man who will

serve you faithfully and well. But the man who is

hasty, unbalanced and violent on the links, will display

the same qualities in the wider field of everyday life.”

PG Wodehouse
