You need golf instruction if you expect to improve your game, unless you are born a natural sultan of swat. A professional golf pro can target the weaknesses in your swing and diagnose your hooks. They can give you secret tricks of the trade and simple mind games to help you better focus before and after every shot on the course.
The best amateur golfers out there take lessons from the pros, even though they might not want to admit it. Natural born athletes like the Michael Jordans and Michael Schmidts of the world even need the pros every once in a while to point out the hitches in their back swing, or how they look up in their short game. Heck, even professional golfers seek out gurus for golf instruction when they re in a slump or losing distance on their drives.
