I hear you Quadruple, I am a proponent of utility analysis regarding what to put most effort in to.
Lets see if we can try to make some landmarks for me then? On how good I should become in each shot?
Putting goals.
Goal 1: Draining 50% of 6-8 footers. Lets call it yards, because then I can make the comparison to meters easier

.
Goal 2: Two putting withing 13-15 yards 90% of the time
Chipping goals:
30 yards from the pin: Within 5 yards ?
20 yards from the pin: Within 3 yards ?
10 yards from the pin: Within 2 yards ?
Those are just suggestions, you are free to give me advice here quadruple.
Pitching goals:
ill write these in meters.
1. Learn how far to take back the club and the proper rythm for a 50, 60 and 70 meter pitch shot with the wedge. If I can master three distances I would be on my way to be a great golfer.
Bunker goals:
1. Get the ball out every time. Im really terrible at this.
2. Learn a flop bunker shot
3. Learn the more rolling bunker shot.
I will make these goals more sofisticated and more difficult later but now Im not good enough so ill keep it simple.
And for my iron and driving game. I will for now not have any goals here, but they will come. My main priority is fighting my out to in swingplane, and I don't need any more goals than that right now.
