Pros miss 40% of greens and fairways on average. Sometimes it is much higher at tougher tracks.
Pros are only 50/50 at 8' putting.
Pros hit bad shots. They simply do everything humanly possible NOT to hit two in a row.

There is much to be learned about one's individual game by tracking their stats in a detailed manner. Do it long enough, and you don't even have to write them down!
Hit 14/18 fairways? What were the 4 misses? Playable? OB? Lost? Wet? There are good misses and bad ones!
GIR are nice, but knowing your misses to the green were of the correct distance (pin high) is critical to knowing your yardages with club selection and course management.
Making fewer three putts makes the biggest and quickest difference on the card. Then eliminating penalty strokes. Those are two major hurdles.

Golf is a continual process. Accepting results and managing expectations are key.
