I am a senior player who is retired and plays or practice golf five days a week. My handicap fluctuates through the year from an 13 to a 10 but never any lower. That means I usually shoot in the mid 80's. My regular course has a rating of 136 from the tees I play. When I play an easier course I can shoot in the high 70's but on my home course breaking 80 only happens once in a blue moon. Question, what do I need to do to do to get a single digit handicap other than moving up to the shorter tees ? I play fairly well for 14 or so holes but it seems there is always one or two blow up holes that wreck a good round.
