playing golf is precisely that, not practicing. i loved playing, and didn't really practice except when i started. though trying to maintain my handicap of 2 some was required.
there's nothing quite like playing, if thats what you enjoy do that.
We have a guy just like the O.P. Started at 32 five years ago......now off 22. We have no idea whether his next shot will kill someone, or he'll belt it down the middle.
I think I have said some unkind things in the past, but now we just let him get on with it.
A bit of practice on the range would do him no harm. Plus the odd lesson.
