Golf is a game of detail. The more attention you pay to detail, to everything, the better golfer you will become.
Allowing yourself time to practice is, of course, the most obvious path to better golf. But while you're out practicing have goals in mind, pay close attention you what you're doing. Practice is a time for relaxed effort, not a time to hack away at a few golf balls.
Experiment with different golf equipment if you can. Try different golf balls occasionally. Find yourself the most comfortable supportive shoes that you can find. You're going to be spending a lot of time in them after all.
As you progress and get mechanically better at your golf swing with Cheap Golf Clubs, perhaps the clubs you once used are no longer suited for you. Don't be afraid to try a stiffer shaft. Keep a close eye on your results. If it doesn't work out after a proper amount of time, go back to what you were doing before.
If you find yourself locked in a self-imposed power struggle with different parts of yourself on the golf course, it is definitely time to have a talk with yourself and ask, "What am I really out here for?"
Enjoy yourself. See if a lower score follows.
But, conversely, don't allow yourself to be thinking about an argument you had the night before with your wife either. Focus your mind to the task at hand while you're on the course. That is simply playing an enjoyable round of golf.
Tell yourself, "For the next few immediate hours I am here, and this is what I doing."
I developed a habit of scribbling in a notepad after each hole the things of notice, good or bad. You don't have to write a book here: "Over compensating for slice", "Tension on putt", "Too much internal negative monologue", "Executed shot from sand trap perfectly".
Afterwards, I go over these notes and get a really good idea of what I need to pay attention to while playing golf.
