I meet a guy who had one of the last single memberships at the FedX Cup Course in Atlanta while hiking in NC.  He recommended Harvey Penick's book to me.  I started playing when I was in my early 60s, and as most golfers do I have good and bad days.  I have had lessons by a good golf pro, even bought new irons.  I improved, but not as much as I thought.  This book helped take what my golf teacher taught me and helped me get my head more in the game.  The book goes over the basics like holding the club, hand position, swing.  But takes you into unusual areas like in your mind swing a bucket of water (you'll have to read the page or two this is on to get the just), but this has helped me with my new (golf pro) grip and the rithium of the swing.  How to take aim and why you should do it with each swing or stroke.  Putting, look at the green the slop, grass, three practice swings (I a more comfortable with two) and believe or even see the ball going in the hole before you strike it.  Don't try to have the ball go too much past the hole when putting.  It is better to have the ball stop just after the hole (this has helped me sink at least 4 or 5 extra putts on 18 holes.  Because if your ball is just loosing momentum at the hole, a lipped put will go in (I do it now quite a few times playing 18), where a little faster put will rim out.  This takes practice because of ripped greens or sloped greens, I still go for a little speed to take out the ball drift, which I usually pay for in a longer second shot.  Another key point which I am just starting to do, and it is paying off.  I take a few clubs after play slows down in the evening (I am lucky enough to have my home back up to the course).  I take a 6 iron, 9 iron, wedge and a putter.  Play one ball all the way to the green.  Then I hit it back to the tee box and start back to the green again.  This has got me use to and better with my swing, irons and short game.  Harvey says only practice this way with one ball.  Never any more and go all the way to the green.  I hit my first ball with the six iron, just in front of the tee box.  I usually hit 4 to 5 irons to get to the green (it is a par 5) depending on my shots, putt out.  Put the ball in front of the green and hit back to the tee box.  This really has improved my short game and putting.  Get and read this book, there is a lot more in it that may help you.
