In golf, over analysis never produces good results. If you’re thinking too much — plotting the shot, rethinking the shot, regripping the club and worrying about the position of the left pinky at the moment of impact — you’re going to fail.
Same thing happens in many marketing departments and small businesses. People get stuck in a rut of overanalysis. They think things to death and worry about all the wrong details. When they finally pull the trigger on something, it flops. Which, of course, makes it even harder to pull the trigger the next time.
