A message arrived from a student asking about getting "cocky" with your swing when things are going well. He asks:
"You started to caution me not to get cocky now that I am hitting the ball solidly. You never finished your thoughts on that and I am interested in what you have to say"
The routine you have for lining up your target and walking into your setup is extremely critical for an accurate position over the golf ball. If you want to have any sort of consistency with your swing, you first need to start with a proper setup.
Your pre-shot routine is important for a variety of different reasons, one of which is your alignment. Everyone has to walk in to the ball before they take a swing, so you must be lined up correctly or else the ball could miss your target drastically.
