A seductive woman's voice begins with meditation exercises, then leads you on a three-hole visualization primer. The author, Sean Ryan, recommends listening to the recording daily for a month, and then before every round, to get the full effect. And he swears to have shaved ten strokes off his scores with the technique. Close your eyes and take a nice deep breath.
Most golfers have a good idea how far they hit their irons in perfect conditions.
You have to check the tops of trees, remember how the wind was blowing on the previous hole and pay attention to the prevailing wind direction throughout the round. The next step is to determine how much longer or shorter the shot will play as a result of the wind. The distance might be 157 yards to the pin, but it will 'play' 177 because of the wind. That puts the player in a good mind-set. Rain, by itself, doesn't have that big an impact.
