If anyone is truly a novice, doesn't have many rounds under their belt or time at the range, getting lessons is sure to help you. People who play a long time without lessons, like me, will usually see a drop off in performance. I had to change everything about my swing since I took my first lesson about five years ago. It has been frustrating at times but worth it. And I say this even though I don't think the lessons I recieved, especially given the number of lessons I took from the individual, were nearly as helpful as they should have been. But it still inspired me to practice more and research more. Practice is the thing. Before I took lessons I hated to hit balls on the range because I hit without purpose. Understanding the swing more gave me a purpose beside just wacking at the ball.
