... and you quit your job and work on that new swing every day. For us amateurs, just think if you didn't have to get in your car and drive to work every day, an only get to play golf when you have a few spare hours every week. Get up, hit the course or range for a full days work on that new swing. Work on it tomorrow the same way. For weeks, then months at a time. Yeah, we'd all have tremendous golf game & length given that amount of practice time ... maybe not PGA caliber depending on inherent talent, but sick game nonetheless.
Reminds me of Paper Tiger... he certainly improved, despite some obstacles along the way.
