Golf is a complicated sport and requires a certain amount of practice to be able to get to a decent level and perform well on the real golf course. Many beginners end up extremely frustrated and lose interest rather quickly. They often want to rush to play on the course and are reluctant to put the necessary time in on the practice range before attempting to play on the real course.
There is a wide variation of putting techniques used among golfers of all levels. These days both experts and average golfers disagree on which putter path is the most advantageous path for hitting consistent, accurate putts. The disagreement is over whether the curve or path should be straight back and through or on an inclined (arced) plane.
