As hard as it will be to contain yourself, don't even contemplate going anywhere near a golf course. Golf is technically quite demanding, and without at least some basic training you'll end up with a lot of frustration. You've seen the top players on TV loosing their cool in frustration, imagine how you will feel if not even a single shot goes where you want it to. Besides, the other people having to wait for you will also not be happy.
As a beginner at the great game of golf, start off at a driving range, take at least four or five lessons, learn the fundamentals, progress to a 9 hole course and eventually venture out into the great unknown of an 18 hole golf course. Believe me, it will be a lot more fun for you and those around you if you follow this path.
You will meet plenty of people at the range who will teach you the 'innermost secrets' of golf. Fact is that most of them have started playing not long before you. So the answer to the above question is: go to a Professional. As you have seen on TV, even the world's top players have a coach and take lessons. Certified Golf Professionals are the only people qualified to teach you how to play the game.
Lessons from a Pro will cost you money but will be the best investment you'll ever make. Taking the advise from the 'know-it-all' people at the range will likely screw-up your game at the very early stage, and it will take a long time to correct the faults later. The two places to get golf lessons are at driving ranges and golf clubs. You don't have to be a member of a club to get a lesson from the Pro. You bring in money, so they will be glad to help. The usual cost is about $25-40 per 45 min, but you will get reductions for a block booking. If you are a bit on the budget see if they do group bookings, those are also cheaper than individual lessons.
As mentioned, books and videos can be invaluable in learning the basics. To build a sound golf swing you will need the three fundamentals: Grip, Stance and Posture. There are some very good books and videos on the market that will help you to establish the three fundamentals. As mentioned earlier, if you're looking for a really comprehensive resource you should consider our 272 page Golf Beginner Guide, our very own in-house publication. It contains every thing you need to know about golf to enjoy it.
Watch the Pro's on the TV, or better still video them and play back in slow motion, you'll learn a lot this way. Don't get blinded by too much science, you're still a beginner. Stick to Grip, Stance and Posture and you'll be on your way. Take a look at our golf tips and golf lessons for some advice.
I hope that this article has been of some help to avoid costly mistakes many people made. Follow the above basics and you are on your way to all the fun (and frustration) golf can offer.
