If you do not have your nerves jumping on the 1st tee you probably are not entirely ready to play! The key to handling your nerves is to redirect the nervousness into focus on the shot at hand. Pick your target and swing to it. Too many times I see players get onto the tee and think about topping the ball or hitting into the trees or water. Also the mind is racing from any or all bad tee shots you have played this year. You just have to block that out and that will help you to get past the nerves. Take a deep breath think about the shot then step in and swing the club. You will be amazed at how well you will do.
