A Lesson in Golf Lessons

I have made it clear that I am not an expert golfer. I'm not even very good. When my girlfriend asked me to take golfing lessons with her, I refused. I continued to play all of last summer without taking a lesson. While my game improved a lot, I developed some bad habits. Habits that a golf instructor would have noticed and corrected. I guess I am a typical man, I never want to ask for directions, because I'm never lost... I also don't want to take any lessons, because I know what I'm doing...
