I had a buddy who always asked me for advice (given that I was at the time a low handicap, and he was, well, a rank beginner). After watching him hit balls while warming up, I walked away with he on my heels. He began peppering me for advice: "Is my grip wrong? Maybe its my hip turn? Do my clubs not fit? What about swapping to a graphite shaft?"
My reply after each query, "Nope, not the problem."
After minutes of frustration on his part, finally he asks, "Well, if i's not one of those, then what is wrong with my game?"
I simply replied, "You're standing too close to the ball after you hit it."
He took up tennis the following week.
