The majority of golfers will never golf below an 18 handicap in their golf careers. For most golfers; golf is actually the quite opposite of a professional sport. It is a hobby or a fun way to spend your weekends. If you're one of those golfers keep knocking back some cold ones and enjoy the fresh air... or the escape of your bickering significant other at home who's building you a list of chores to do on your day off.
Professionals typically play a 4-6 handicap before getting into the professional play of the sport. To get to this point takes a lot of practice and commitment or to be gifted in the sport.
