Why is the golf swing so difficult?

Through the website Quora I recently was asked to answer the question, "Why is the golf swing so difficult?" I thought about it for quite awhile and below is my response. 

     The golf swing itself is not a difficult motion, but rather the proficiency required to become a good player. Let me give you an example: Most anyone has the physical ability to attempt shooting a free throw in basketball or to roll a bowling ball down a lane. The same is true for tossing a horseshoe or pitching a dart. But how many people can make ten free throws in a row, make ten strikes in a row, throw ten ringers in a row or hit the bulls eye 9 out of 10 times with a dart?

     That’s where the proficiency comes into play. These individuals have spent years practicing to develop their skills. The golf swing is no different. It doesn’t require an extraordinary amount of athleticism to swing an object weighing less than a pound to propel a ball weighing less than two ounces. It does however require a tremendous amount of practice to develop the skills and proficiency to hit shots with any level of consistency.

     Most individuals possess the necessary physical attributes to play golf at a reasonable level. A player’s determination, work ethic and mental attitude will have a lot to do with how good a player they become.
