When I first started playing regularly, I just happened to join up with a threesome on the first tee. At that time I was pretty crap and was just learning the fundamentals of the game.
Don't know whether it was nerves being with 3 total strangers, but I had an awful front nine.
There was a snack bar (sold beer too) at the 10th tee, and one of the fellas bought a round for his 2 mates and asked me if I'd care for a beer, which I gladly accepted.
As he handed me the bottle, he asked me if I minded him saying something he'd noticed about my grip. As I always liked getting feedback from better golfers, I said please do.
He said my grip was fine except for one thing. I was holding the clubshaft too tightly.
He said imagine you are lightly holding a bird's feather between the shaft and your lower hand's third finger. Then imagine the pressure on the feather at point of impact with the golf ball is loose enough to dislodge the feather so it falls out of your grip to the floor.
That's all the pressure you need on the shaft.
Best tip I've ever had - my game improved immeasurably from that point on ! So simple, just one of many factors your muscle memory needs to learn to hit the ball consistently.
I just zigzagged down the rough with my long suffering caddie asking me if it was my first time. I had a swing like a frog in a blender.
