Golf has helped contribute to my carreer success in a big way. I often said I have done more business on a golf course or as a result of it than in an office. Where else can you get 5 hours of uninterrupted time with business associates and customers
You dont have to be good just competent so that you fit it. More important is to know the protocol of the game: where to stand, when not to talk, the order of play. They say you learn a lot about someone on a golf course.
Most golf outings are scrambles which takes off the pressure to score low. The expectation is that each player makes a contribution along the way. I will say that being a low handicap player does confer an amount of competency on you. The thought is that if you are a good player then you must be a good person. Fair or not, it's the truth
So, learn enough to contribute, never ever cheat, correctly score, if you are the business host understand who pays for what, learn where to stand and when to shut up
