Obviously I dont' speak for everyone but this is my approach to a round of golf, I arrive at the club an hour before I tee off and have a light breakfast. I dont' spend too much time at the practice range other than hitting about a dozen balls, I prefer to spend my time hitting a few chip shots and on the putting green. I also prefer not to keep score, I am always ready mentally, swing thoughts are at an absolute minimum. I attempt to play my round one shot at a time applying my best effort on each and every shot whether it be a drive or a short putt. Nibble on something between holes and carry some bottled water, pace yourself, relax and enjoy your surroundings. It works for me.
