More detailed instruction is available through the Order Services link. Playing golf, like any game, is a game of chance. But like any game, your performance is determined by how skillfully you play, and luck. The amount of luck influencing the outcome of a game depends on the game itself. Golf is a game which is most greatly influenced by the skill level of the player.
Luck plays only a minor roll even though some days it does appear to be a major factor.
In order to improve at golf, one must improve one or more of the many facets of the game. One could work on the full swing and ball striking. One could work on the short game such as wedge play, sand play, chipping and putting. One could focus on improving the mental side of the game such as controlling emotions and using visualization to improve concentration. One could also just try to improve performance, not by improving any particular skill level, but optimizing the odds of play.
