Simply worry about your own game.  Stick to your best, don't try and gain 30 yards if you are outdriven.  Keep it in play, make alot of pars and capitalize when you can.  Winning tho, isn't the only thing, I have always taught me kids, be polite, saying, nice shot, good putt.  Make sure to take the flag stick out, and put it back in.  Fix all pitch marks, yours and theirs and any spotted.  Just be yourself and allow the game to surround you and it will fall into place.  Have fun and enjoy it, don't take any added pressure out there with you.  As far as golf tips, I very rarely warm up with a driver, normally start with a few 7i, drop to a few PW, then alot of 4i, as the long irons might be the fewest I hit in a round, but the better they are hit, generally, the better all clubs are hit.  Then off to the chipping / sand and then onto the green for putting.  If I have time left, I go back and hit 3-5 range shots with the driver and then to the first tee.  Make sure to have a snack, drink and a smile, as your about to spend 4+ hours golfing.

Good Luck
