Drill: 30 in a row - Surround a hole with 6 balls, each a foot from the cup.  Sink all six, then place them at two feet from the hole and repeat.  Move the balls out at 1 foot increments until you sink 6 five foot putts. 

The Catch:  Anytime you miss, you have to start over with the 1 footers.  You may never sink 30 consecutive putts, but the pressure of trying will ready your nerves for the course.

"I guess there is nothing that will get your mind off everything like golf.  I have never been depressed enough to take up the game, but they say you get so sore at yourself, you forget to hate your enemies."
