I've been lurking here for the better part of a year but your post
motivated me to register and reply.
First of all, I FEEL YOUR PAIN. :)
I have lost my swing on many occasions.
It is so frustrating... Makes a grown man wants
to cry... Until I realized I am not good
enough, and do not play enough golf to get angry.
I also 'found' the swing again each time I lost it.
This is what I learned through those
process.
When I lost the swing, I really never had it.
I may have
had one or two pieces of the swing, and by dumb luck,
grooved into enough of the missing pieces by swinging one
club over and over again on the range. But I had no idea which
pieces I had, which one I stumbled on to. It's hard to bring
dumb luck with you to the range/course every day.
Each time I found the swing again, I found another piece of the
swing that I did not have a handle on before. It also takes less
time to find the 'lost swing' each time I lost it. The swing that
I 'found' again, has always been better than the one I 'lost.'
I also changed my range sessions. I used to swing one club
for a while, switch to another club for a pile of balls, and so on....
After enough bad shots, you could adjust....
But you only get one shot on the course...
Now, on the range, (for me, your mileage may vary,) I do not
swing one club over and over again. I swing a long club, 3i/2H
(not good enough to game a driver yet) at
a target, then switch to a mid iron/short iron at a target, then switch
to a wedge at a target.
Enjoy the game.
Good luck.
