I know of a method that will guarantee you a lower handicap.

It's called the "Lessons and loads of practice" system.

Firstly you go to a pro for the "lesson" stage.
This stage is usually repeated once a month.

Then you go to the range/practice area for the "practice" stage.
This stage is repeated as often and for as long as possible.

Combine the result of both stages on the golf course.

Follow this system and your handicap will drop.
