As a beginner you could have just one major fault or a combination of many minor ones. The swing is a series of actions, the address, the grip and the swing. Athough other aspects can come into the process like your body and the speed of your swing. When you begin to play golf, you will require professional instruction. As well as understanding the basic aspects of the swing you also need to know how to shift you body weight as you undertake each swing.
Once practicing these basics, if you discover that you do not progress as quickly as you would like this may well be down to your instructor. At this stage of your learning you need a good relationship with your instructor. If not, your swing will not develop. What many people do at this stage of learning is to obtain one of the many eBooks that are available to assist you. Certainly when I was a beginner not only did one professional contradict the instruction of another, some times they were even wrong with their instruction. I certainly improved further by having a guidebook, I obtained from the internet far more quickly than I ever did with the professionals.
The guide that I used was ‘The Simple Swing’. It practically started my game from the beginning all over again. It was uncomplicated to understand, had first-rate illustrations and went to the very foundation of my problems. The majority of Pro's will not get to the crux of your problems. They teach simply what they believe that you will understand. So, as a student you miss out on a number of the more central aspects of the swing. As a result you will struggle, as certain aspects of the instruction have been kept from you. Patience and practice of the simple swing method will enhance your game.
Whilst it may take you a considerable time to acquire a good golf swing, you will be rewarded in the end. This process cannot be rushed. Do not expect to read a guide one day and take all of this fresh information to the course the next day. It does not work that way. Read your guide compare it to how you play. Correct things down the range but most of all practice a few times before you go to the course. The golf swing is the one skill that most golfers spend more time on than any other skill so, practice and improve this part of your game so, that you can improve your game overall.
