Golf is very much like Vegas. Right when you've hit your last crappy shot and you're ready to throw your clubs in the lake, golf sucks you right back in with a shot that could be on a PGA tour highlight reel. Like mentioned before don't over play. I'm notorious for playing down to my groups abilities. I've started taking my game more serious because I want to be good. I regularly shoot in the 80s, good round is 81- 82. But damn if I don't lose all skill when I play with two of my buddies. I shot an 85 and seven days later shot a 106 on the same damn course!!!!! Drives me crazy. But a couple tips I give friends or people playing early in their golf life
1- we won't be hitting the same club. Just because I pull a 9 doesn't mean you should hit a 9. Hit what you normally hit. As long as its straight its playable. Even if its a worm burner straight way better then lost left or right. We won't be hitting the same club very often.
2- don't try pga chips. Grab a 7 or 8 and use a putting stroke, not as cool looking but way easier and way more effective for high handicappers.
3- know why you're golfing. Are you golfing just to chill with the boys or are you golfing to be a good golfer. Can't have it both ways. I know some people will disagree but the mindset is completely different and so is the atmosphere.
4- if you only golf a couple times a month and don't practice then don't trip on your scores. Flipside if you're a range warrior but hardly play then don't trip on your scores either.
5- 3 or more putts. Those will kill new golfers. If you practice putting and can get half way decent at putting and are not 3 or more putting you are looking at 18- 30 strokes gained. Tee to green will come with playing more.
Lastly- ask your group to watch your ball. This is a way overlooked problem with amateur golfers, we don't have marshals and cameras watching our shots so what do we all do? Pick our freaking heads up and top the crap out of the ball. Ask your buddies to watch your shot so you can concentrate on keeping your head down and watching the ball.
