Hi.
One of the benefits of being left handed is i always tee off with my back to my buddies so i never get first tee nerves.

Let me suggest that you work on developing a sound pre-shot routine. When tom Kite felt first tee nerves, because he had a solid pre shot routine, just a little thing like opening and closing the velcro fastener on his glove would calm his nerves immediately becuase that was the SIGNAL to his sub-concious to start his pre shot routine. then nothing else around him mattered.

Hope this helps.......regards.... T.P.Grealey
