You want a lower golf score but you're not very strong off the tee. Actually that's ok. The old saying that you drive for show and putt for dough is just absolutely take it to the bank true. The only part they left out was the importance of the short game.
Think about it for a second. What's the club you use the most in a round of golf. It's also the club that you will use on every hole unless you get really lucky with a chip shot. It's the putter of course.
You say you're putting isn't so hot either? Well is it your putting or is it the approach shot that left you 30 feet away that's causing the problem? Your approach shots and putting are where you score. If you have limited time to practice, putting and shots from 100 yards and in are what you should be focusing on.
Let me take that back. The first shot that you absolutely have to master is a shot that will go 150 yards every time you hit it. It doesn't matter what club you use, you just have to have confidence that it is going to travel that distance and land where you want it. If you can develop a 150 shot you'll be hard pressed to play a round greater than bogey golf.
Why is that? Well just do the math. How many 150 shots are there in a 420 yard par 4. That's right. You could tee off with your 150 shot and be on the green in 3. Two putts later and you finish with a bogie. Think that one through for a moment. If you put away your big banana driver and brought out your three wood on the tee, odds are you will hit the fairway as the three wood, being a more lofted club than the driver, takes the right to left spin off the ball and goes straighter.
Maybe that drive only goes 180 yards but it's playable. Now you are left with 240 yards to the pin. Are you going to play the three wood again? No you are not. You are going to play your trusty 150 club and leave yourself 90 yards to the pin.
Two things are in play here. First attempting to hit 240 yards using a club you just teed off with that only went 180 yards does not inspire any confidence. You're likely to want to crush the ball and that only leads to disaster doesn't it. However, if you know your next shot is going to go 150 yards you can decide how you want to approach the green which will give you a better opportunity than just wailing away.
You may have the dating habits of the Woodster but you know you don't have his golf talent. Just play within your game and you'll end up with a lower score. The more that occurs the more confidence you'll have and the better you'll play.
If all this doesn't work, carry a pencil with an eraser.
