I'm a 5 and to me the most important thing is greens in regulation. This and good course management. I think simply getting the ball in play off the tee (vs distance) thus giving me the best chance to hit the green. Then I try to two-putt at worst. Practice chipping to save the pars. Also mark down on the score card if your approach shot was short, on, or long. This is a very telling thing as most golfers are short most of the time.
