Golf is a great game!
The first thing to realize is that there is only ONE Tiger Woods. Does this mean your child will never play at the professional level? No. What it means is that Tiger was a true prodigy that was driven very hard by his father, but was a rare child who did not burn out on the sport, nor did his focus and determine wane to this day.
Your child's chances of playing in college and at the professional level are the same as in every other sport, very slim.
The best advise for getting your child started in Golf is to enroll them into a Junior League at your local golf course.
