I always get nervous for the first hole or two in a round because I don't want to ruin the round with a bad score in the beginning. So what I try and do is just visualize the ball flight and say to myself your just hitting a ball with a club out in a field somewhere. It puts things in perspective and helps to relax me because I don't think of all the things I need to do with my swing I just swing the club like I've programmed myseld to do with my pre round practice.
