I always found that if I put in the time and the effort to prepare for the event I always did better on the first tee. I would also remind myself that this shot carries no more weight than any of the other shot I would hit that day. They all count 1. Is it important to start the round off well? You bet. The first shot should not make or break a round. There are plenty of shots left to hit. But it is nice to start the round off well!
