Start with the math
On a par-72 course, 89 can be 17 bogeys and one par. That is not flawless golf. It is golf without a pile of doubles and triples.
Choose a safe target
Aim for the widest part of the fairway and the middle of the green. You do not need to attack every flag.
Know when to put driver away
If trouble squeezes the landing area, a shorter club that stays in play may save more shots than an extra 30 yards.
Your next-round assignment
Track penalty strokes, three-putts, and doubles. Practice the category costing you the most.
