What if I hear the group(s) behind us yelling a lot?

I hate to be the bearer of bad news, but it is more than likely that you are holding everyone up.  You are the slow golfer everyone is talking about.  Some tips – stop looking for golf balls when yours is in the fairway, stop taking 7 practice swings just to hit the ball 10 yards, stop watching everyone else’s shot when you don’t even know where your ball is, stop spending so much time deciding which club you are going to miss the green with, or just simply walk to your ball quicker.  Everyone will thank you.
