Have you ever heard of the acronym K.I.S.S.? If you haven't it means keep it simple stupid (or sweetie if you want to say it more nicely). This acronym can be useful to your golf game. Keeping it simple will allow you to focus better when you step up to the tee.
When you make things complicated, you may become flustered when you are trying to remember too much at once. If you aren't worried about a hundred other things you will be able to focus more on the task at hand, your swing. Loosing focus can mean your ball going into a sand trap.
The more you practice your golf swing, the better. This will allow you to not have to put a lot of thought into the mechanics of your swing when you are stepping up to the tee. You want to be able to visualize the path that the ball will take.
Exercise is also an important part of golfing. Many people do not see golf as a sport, but that is only because they do not understand the sport. In order to achieve great distances in your shots, you need the strength behind that swing. Exercise will keep you healthier and improve your strength. Both of these will aid in improving your swing.
If you want to improve your game, learn and master the golf swing basics. Then find your own perfect swing. By mastering the basics you can impress your golfing buddies the next time you step out onto the green.
